BACKGOUND : The recycling of valuable metals from spent lithium-ion batteries (LIBs) has attracted much attention. This work investigated the recovery of cobalt (Co), nickel (Ni), copper (Cu), iron (Fe) and manganese (Mn) from metallic alloys generated from the reduction smelting of spent LIBs by a hydrometallurgical process. RESULTS : The complete leaching conditions for metals from the alloys were optimized as: 2.0 mol L-1 hydrochloric acid (HCl), 5% (volume/volume) hydrogen peroxide (H₂O₂) with 30 g L-1 pulp d. at 60 °C within 150 min. Metal ions such as Co(II), Ni(II), Cu(II), Fe(III), Mn(II) and silicon [Si(IV)] from HCl leachate were separated sequentially in four steps using solvent extraction and oxidative precipitation First, Fe(III) was completely extracted over others using 0.5 mol L-1 Di-(2-Et Hexyl) phosphoric acid (D2EHPA). Second, Cu(II) from the Fe(III)-free raffinate was selectively extracted using 0.25 mol L-1 Cyanex301. Fe(III) and Cu(II) were quant. stripped from their loaded phases using 50% (volume/volume) aqua regia. Third, Co(II) from the Fe(III)- and Cu(II)-free raffinate was selectively extracted over Ni(II), Mn(II) and Si(IV) with 0.25 mol L-1 ALi-SCN and stripped with 10% (volume/volume) ammonia (NH3). Finally, Mn(II) from the raffinate containing Ni(II) and Si(IV) was separated at pH 3 by oxidative precipitation of MnO₂ after adding 10% (volume/volume) sodium hypochlorite (NaClO). Mass balance anal. of the whole process indicated that the recovery and purity percentage of the metal ions were >99.9%. CONCLUSION : With its effective and selective performance, the application of this process to real-life recovery of valuable metals from spent LIBs can be considered. 2021 Society of Chem.

Selective separation of cadmium(II), copper(II) and nickel(II) ions from electroplating wastewater using dual flat sheet supported liquid membrane was written by Lee, Lai Yee;Morad, Norhashimah;Ismail, Norli;Rafatullah, Mohd. And the article was included in Desalination and Water Treatment in 2021.Formula: C25H54ClN The following contents are mentioned in the article:

A dual flat sheet supported liquid membrane (DFSSLM) system was developed based on concurrent extraction, selective separation, and recovery of three metal ions from a mixture in a single process. DFSSLM was made up of a combination of two membranes and three compartments (feed, intermediate and strip) to selectively recover not just one but three types of metal ions at the end of the system. This research aims to study the efficiency of DFSSLM in the selective extraction of cadmium(II) and copper(II) over nickel(II) ions from an aqueous mixture and electroplating waste-water. The first membrane was impregnated with 100 mM di-(2-ethylhexyl)phosphoric acid and 50 mM tri-Bu phosphate in kerosene, whereas the second membrane was impregnated with 99.64 mM trioctylmethylammonium chloride and 50 mM tri-Bu phosphate in toluene. After continuous stirring (500 rpm) in all compartments for 48 h, 98.79% of nickel(II) was recovered from the synthetic mixture in feed, 91.32% of copper(II) in intermediate, and 91.04% of cadmium(II) in strip compartment. The flux changes and kinetic studies showed cadmium(II) was preferentially transported over copper(II). The membranes (polymer and extractants) were characterized by Fourier transform IR spectroscopy and SEM with an energy-dispersive X-ray. In comparison with the treatment of real electroplating effluent, high output/input ratios were obtained for recovered cadmium(II), copper(II) and nickel(II). Most of the other heavy metals were eliminated together with the recovery of 89.09% of cadmium(II) in the strip, 90.87% of copper(II) in intermediate, and 97.61% of nickel(II) in the feed. This study concluded that DFSSLM is efficient for the separation and recovery of cadmium(II), copper(II) and nickel(II) from a complex mixture This study involved multiple reactions and reactants, such as N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3Formula: C25H54ClN).

This study investigates the recovery of Zn(II) and Cr(III) from aqueous solutions based on solvent extraction with trioctylmethylammonium chloride [TOMA⁺][Cl-], commercialy named Aliquat 336. Single metal solutions and binary mixtures of both metals were considered. The effect of relevant operating conditions such as pH, contact time, initial concentration, O/A phase volumetric ratio, and temperature were evaluated. Addnl., loading capacity and stripping studies were performed. Results showed that [TOMA⁺][Cl^–] is an effective extracting agent for Zn(II), reaching maximum removal capacity at pH 1.8 and demonstrating fast extraction kinetics. Extraction efficiencies above 99% were achieved at 0.5, 0.75, and 1.00 O/A volumetric phase ratios for 0.1 g/L initial Zn(II) concentration At 1 g/L and 10 g/L concentration, for the same O/A ratios, approx. 88% of the initial Zn(II) was extracted In contrast, it was found that negligible amounts of Cr(III) were transferred to the [TOMA⁺][Cl^–] phase at the 1-5 pH range. Selectivity studies showed that Zn(II) removal is boosted in the presence of Cr(III), although no Cr(III) is extracted [TOMA⁺][Cl^–] exhibited a high Zn(II) storage capacity, since after 25 loading cycles with 1 g/L, the loading capacity reached approx. 13.5 g/L, and after five loading cycles with 5 g/L, the capacity reached 19.4 g/L. Stripping tests revealed that NaOH is an efficient agent for the removal of Zn(II) from the ionic liquids, reaching 98.5% removal after two cycles, whereas HNO₃ is not a suitable agent, reaching less than 40% removal after three cycles. [TOMA⁺][Cl^–] revealed high potential for separating Zn(II) from Cr(III).

Recovery of Cobalt, Nickel and Copper Compounds from UHT Processed Spent Lithium-ion Batteries by Hydrometallurgical Process was written by Tran, Thanh Tuan;Moon, Hyun Seung;Lee, Man Seung. And the article was included in Mineral Processing and Extractive Metallurgy Review in 2022.HPLC of Formula: 5137-55-3 The following contents are mentioned in the article:

Lithium-ion batteries (LIBs) are employed in various electronic devices and industries. The recovery of valuable metals from spent LIBs has attracted much interest due to potential environmental issues and economic values. Metallic alloys can be obtained from the UHT process of spent LIBs. In this study, a hydrometallurgical process was developed for the recovery of metal compounds from synthetic metallic alloys containing Co, Ni, and Cu. This process consisted of leaching, solvent extraction, stripping and precipitation First, the metallic mixtures were completely leached by the mixture of 2.0 moL·L^-1 HCl and 10%(volume/volume) H₂O₂ solutions at 60°C. Metal ions in the leachate were sequentially separated by solvent extraction with 0.7 moL·L^-1 Cyanex301 and 1.0 moL·L^-1 Aliquat 336 for Cu(II) and 1.0 moL·L^-1 ALi-SCN for Co(II), whereas Ni(II) was remained in the final raffinate. The compounds of Cu(II) and Co(II) were recovered from the resp. loaded organics by precipitation stripping method, while Ni(II) compounds were recovered by precipitation from the final raffinate without changing its acidity. Mass balance of the whole process indicated that the recovery percentage of metal compounds such as CuC₂O₄, CoCO₃, and NiC₂O₄ · 2 H2O was 98.6, 99.4, 99.8% from the leaching solution and the purity of the compounds was higher than 99.9%. A process was proposed for the recovery of pure metal compounds from spent LIBs. The advantages of this process are the possibility that metal compounds with high purity can effectively be synthesized and the aqueous raffinates and the stripped organic solutions after each step can be recycled.

Combining of modified QuEChERS and dispersive liquid-liquid microextraction as an efficient sample preparation method for extraction of acetamiprid and imidacloprid from pistachio samples was written by Khanehzar, Hasan;Faraji, Mohammad;Nezhadali, Azizollah;Yamini, Yadollah. And the article was included in Journal of the Iranian Chemical Society in 2021.Recommanded Product: 5137-55-3 The following contents are mentioned in the article:

In this research, for the first time, the QuEChERS was combined with the dispersive liquid-liquid microextraction based on deep eutectic solvent (QuEChERS-DES-DLLME). The method was developed for efficient extraction, clean-up and preconcentration of acetamiprid (ACE) and imidacloprid (IMI), two commonly used pesticides, from pistachio samples before their determination by HPLC-UV. The pesticides were firstly extracted from pistachio samples and cleaned-up by QuEChERS, and then their supernatant was used as a dispersant in following DLLME in order to further purification and preconcentration The extraction solvent used in DLLME was based on deep eutectic solvents (DESs). Preparation of hydrophobic DES was done by mixing amyl alc. as hydrogen bond donor and trioctylmethylammonium chloride (TOMAC) as hydrogen bond acceptor. Different parameters that affect the efficiency of the two steps were evaluated and optimized. Under optimal conditions, the limit of detections was 1.5 and 3.0μg kg-1 for ACE and IMI and the limit of quantification was 1.5 and 4.5μg kg-1 for ACE and IMI, resp. Calibration curves were linear in the range 5.0-500μg kg-1 with correlation coefficients higher than 0.99. Preconcentration factor for ACE and IMI was 16 and 13, resp. The intraday and interday precisions at concentration levels of 10 and 100μg kg-1 were less than 7.0%. Finally, applicability of the suggested method was investigated through anal. of the analytes in some pistachio samples, and the obtained relative recoveries (95.6-99.4%) were acceptable. The good sensitivity and suitable purification in the anal. of the pistachio samples, as a complex food matrix, are obtained using the proposed method by combining the advantages of QuEChERS and DLLME.

A critical challenge in the enrichment of active ingredients in natural medicines is the design of adsorbents with high selectivity and adsorption capacity. Covalent organic frameworks (COFs), which have adjustable pores and high sp. surface areas, could be effective as adsorbents for active ingredients. This study used an environmentally friendly deep eutectic solvent (DES) instead of organic solvents as the reaction solvent, and high-crystallinity COF-DES was successfully prepared The COF-DES fabricated using 1,3,5-tris(4-aminophenyl)benzene and 2,5-dihydroxyterephthalaldehyde as building blocks showed good dispersibility, large surface area (444.56 m²·g^-1), and suitable pore size (25.9 Å). Owing to its unique structure and functional group properties, COF-DES can prevent interferences from other compounds such as alkaloids, resulting in outstanding selective adsorption performance for flavonoids. Furthermore, under optimized adsorption conditions, the adsorption effects of the COF-DES on flavonoids were much better than those of the effects of macroporous resins, indicating the potential of the COF-DES as a selective adsorbent for flavonoids. Finally, a flavonoid-possessing rich natural medicine, Abelmoschus manihot (Linn.) Medicus flower, was used as a sample to study the application potential of the COF-DES. The results showed that the COF-DES had good adsorption and selection capability for flavonoids in actual samples. Moreover, compared with solid-phase extraction (SPE) columns based on macroporous resins, a COF-DES based SPE column showed superior adsorption performance for an actual complex sample, indicating the potential to COF-DES as an effective adsorbent alternative to macroporous resins. Addnl., the COF-DES had great com. value as an adsorbent for SPE flavonoid columns.

Separation of Re(VII) from Mo(VI) using biomaterial-based ionic gel adsorbents: Extractive adsorption enrichment of Re and surface blocking of Mo was written by Li, Wenjing;Dong, Xuelin;Zhu, Lihua;Tang, Heqing. And the article was included in Chemical Engineering Journal (Amsterdam, Netherlands) in 2020.Formula: C25H54ClN The following contents are mentioned in the article:

It is urgently needed to develop highly efficient and selective adsorbents for enrichment and separation of Re(VII) from Mo(VI) to obtain metallic rhenium. By tuning cross-link of chitosan, ionic gel capsules (CSN) were prepared, which had a core-shell structure and wrapped N263 (Me trioctyl ammonium chloride) as an extractant. After being characterized, the CSN capsules were used as a green adsorbent for separation of ReO^–₄ from MoO^2-₄. It was found that the gel yielded good adsorption capacities for Re(VII) in a wide pH range from pH 2 to 12. The adsorption of Re(VII) on the gel followed the Langmuir model, exhibiting a maximum adsorption capacity of 222 mg g^-1 for Re. The adsorbent showed good adsorption capacities for Mo(VI) at pH < 2, but little at pH > 3.5. Therefore, the enrichment and separation of Re(VII) from Mo(VI) could be easily achieved by using the gel adsorbent in a wide pH range from 4 to 12, showing a separation factor β_Re/Mo with values of 10³-5 × 10⁴. A mechanism was proposed for the selective adsorption of Re(VII). The extractant N263 wrapped in the capsule core provides excellent extractive adsorption ability for Re(VII) through ion association extraction, generating ion association complex R₄N⁺•ReO^–₄ in the adsorbent. The gel shell was composed of cross-linked chitosan induced by sodium tripolyphosphate, and functioned as a blocking layer for the adsorption of Mo(VI), being possibly related to a special interaction between Mo and P as observed in the formation of phosphorus molybdenum heteropolyacid and/or the crosslinking with Mo and chitosan. The CSN gel was successfully applied to sep. ReO^–₄ from a practical alk. solution This study involved multiple reactions and reactants, such as N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3Formula: C25H54ClN).

Host-guest solution chem. with a wide range of organic hosts is an important and established research area, while the use of inorganic hosts is a more nascent area of research. In the recent past in a few cases, Keplerate-type molybdenum oxide-based porous, spherical clusters, shorthand notation {Mo₁₃₂}, have been used as hosts for organic guests. Here, authors demonstrate the synthetically controlled encapsulation of first-row transition metals (M = Mn, Fe, and Co) within a Keplerate cluster that was lined on the inner core with phosphate anions, {Mo₁₃₂PO₄}. The resulting M²⁺_x⊂{Mo₁₃₂PO₄} host-guest complexes were characterized by ³¹P NMR and ENDOR spectroscopy that substantiated the encapsulation of the first-row transition metal guest. Magnetic susceptibility measurements showed that the encapsulation of up to 10 equiv showed little magnetic interaction between the encapsulated metals, which indicated that each guest atom occupied a single site. Visualization of the capsules and differentiation of the Mo atoms of the capsule framework and the encapsulated transition metal were possible using spherical and chromatic double aberration-corrected electron microscopy combined with energy-filtered TEM (EFTEM) elemental maps. In addition, use of visible light-induced XPS for chem. resolved elec. measurements (CREM) confirmed the successful encapsulation of M within {Mo₁₃₂PO₄} and furthermore showed photoinduced electron transfer from M to Mo. In the future, such targeted electron transfer between host {Mo₁₃₂} and a transition metal guest could be used as photoinitiated switches using inorganic compounds and for single site photocatalytic reactions in confined space.

The effect of solvent on the binding of anions and ion-pairs with a neutral [2]rotaxane was written by Molina-Muriel, Ricardo;Romero, J. Ramon;Li, Yifan;Aragay, Gemma;Ballester, Pablo. And the article was included in Organic & Biomolecular Chemistry in 2021.Safety of N-Methyl-N,N-dioctyloctan-1-aminium chloride The following contents are mentioned in the article:

In this work we report the binding properties of rotaxane 1 towards a series of tetraalkylammonium salts of Cl^–, OCN^– and NO₃^– anions in acetone and a CHCl₃/MeOH solvent mixture We used ¹H NMR titrations and Isothermal Titration Calorimetry (ITC) experiments to monitor and analyze the binding processes. We compared the obtained results with those previously described by us in chloroform solution In acetone solution, the determined binding constants for the 1:1 complexes were 1 to 3 orders of magnitude larger than those measured in chloroform, a less competitive solvent for hydrogen-bonding. The thermodn. signatures of the binding processes in acetone, determined by ITC experiments, revealed favorable enthalpic and entropic contributions having similar magnitudes. These results suggested that solvation/desolvation processes in acetone play a significant role in the binding processes. Conversely, the addition of just 5% of methanol to chloroform solutions of 1 significantly reduces the magnitude of the binding constants of all studied ion-pairs. In this solvent mixture, the entropy term is also favorable but it does not compensate the experienced loss of binding enthalpy. Moreover, in acetone solution, the addition of the Cl^– and OCN^– tetraalkylammonium salts in excess (more than 1 equivalent) led to the immediate appearance of 2:1 complexes. Related high-stoichiometry complexes are not observed in the solvent mixture (CHCl₃/MeOH 95/5). In chloroform, a large excess of the salt (> 6 equivalent) is required for its formation. From the anal. of the obtained binding data we infer that, in acetone and in CHCl₃/MeOH mixture, the formed complexes are mainly anionic.

Tunable Nitrogen Defects on Graphitic Carbon Nitride toward the Visible-Light-Induced Reversible-Deactivation Radical Polymerization was written by Han, Shiwei;Qiu, Teng;Xiong, Chongwen;Li, Xiaoyu;Guo, Longhai. And the article was included in Macromolecules (Washington, DC, United States) in 2022.Electric Literature of C25H54ClN The following contents are mentioned in the article:

Introducing nitrogen defects has been confirmed to improve the photoactivity of graphitic carbon nitride, but this strategy is far from being employed in the field of photo-polymerization Here, the nitrogen-deficient graphitic carbon nitride (g-C₃N_x) is proposed as an effective photocatalyst for photoinduced electron/energy transfer reversible addition-fragmentation chain transfer (PET-RAFT) polymerization under visible light. The g-C₃N_x was prepared through the thermal polymerization of melamine with the pre-treatment by using the different kinds of preparation tailoring agents (PTAs). It has been revealed that both the amount and the type of the PTA have a profound impact on the reaction rate and the induction period of this visible-light-driven PET-RAFT polymerization, attributed to modulating the optical absorption boundary and the carrier transport efficiency of g-C₃N_x by the introduced defects of nitrogen vacancies and cyano groups. Under the optimal condition with 0.5 g of NaOH being employed as the PTA, a monomer conversion higher than 90% was obtained in the PET-RAFT polymerization, almost doubled in comparison to the conversion catalyzed by pristine g-C₃N₄ under the parallel 10 h of blue light (λ_max = 465 nm) irradiation, and the induction period was also dramatically shortened. The as-synthesized polymers exhibit a kinetically controlled mol. weight with low dispersity (PDI < 1.2). Moreover, high end-group fidelity, universal monomer/chain transfer agent adaptation, and reliable reused capability are shown on the 2D sheets of g-C₃N_x being applied as the potential semiconductor catalyst for PET-RAFT polymerization under visible light.
