The purpose of this study is to explore the pickering emulsion liquid membrane (PELM) performance for removing divalent lead ions (Pb II) from aqueous solution In the present work, the membrane phase was prepared by dissolving methyltrioctylammonium chloride (Aliquat 336) with Mahua oil and adding oleic acid coated-ferrosoferric oxide (OA-Fe₃O₄) as magnetic nanoparticles. Exptl. investigation on percentage removal of lead ions was carried out by studying the influencing process parameters such as pH, agitation speed, stripping concentration, initial feed concentration, surfactant concentration, treat ratio, M/S ratio and carrier concentration The optimum condition to remove 98.52% of lead ions from the feed solutions has achieved at a stripping phase concentration of 0.3 M, treat ratio of 3, agitation speed of 300 rpm, initial feed concentration of 10 ppm and stabilizer concentration of 2 wt%. The exptl. results were validated using box-behnken response surface methodol. The extraction ability of OA-Fe₃O₄ magnetic nanoparticles-based PELM has been evaluated using statistical optimization of all the affecting process factors using the design of the experiments This study involved multiple reactions and reactants, such as N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3Recommanded Product: 5137-55-3).

Comparative Studies on the Structure-Performance Relationships of Phenothiazine-Based Organic Dyes for Dye-Sensitized Solar Cells was written by Li, Shengzhong;He, Jingwen;Jiang, Huiyun;Mei, Shu;Hu, Zhenguang;Kong, Xiangfei;Yang, Miao;Wu, Yongzhen;Zhang, Shuhua;Tan, Haijun. And the article was included in ACS Omega in 2021.Category: chlorides-buliding-blocks The following contents are mentioned in the article:

A D-A-π-A dye (PTZ-5) has been synthesized by introducing a benzothiadiazole (BTD) unit as an auxiliary acceptor in a phenothiazine-based D-π-A dye(PTZ-3) to broaden its spectral response range and improve the device performance. Photophys. properties indicate that the inclusion of BTD in the PTZ-5 effectively red-shifted the absorption spectra by reducing the E_gap. However, the device measurements show that the open-circuit voltage (V_oc) of PTZ-5 cell (640 mV) is obviously lower than that of the PTZ-3 cell (710 mV). This results in a poor photoelec. conversion efficiency (PCE) (4.43%) compared to that of PTZ-3 cell (5.53%). Through further comparative anal., we found that the introduction of BTD increases the dihedral angle between the D and A unit, which can reduce the efficiency of intramol. charge transfer (ICT), lead to a less q_CT and lower molar extinction coefficient of PTZ-5. In addition, the ESI test found that the lifetime of the electrons in the PTZ-5 cell is shorter. These are the main factors for the above unexpected result of PCE. Our studies bring new insights into the development of phenothiazine-based highly efficient dye-sensitized solar cells (DSSCs).

Vincristine has a wide spectrum of clin. activity and is currently used in the treatment of leukemia. Despite its high therapeutic properties, vincristine has common side effects. Accordingly, it is desirable to determine vincristine in plasma for the use of the drug with strict monitoring. In the present research, for the first time a hydrophobic deep eutectic solvent (DES) composed of methyltrioctylammonium chloride (MTOAC) and n-butanol in a molar ratio of 1 : 3 was used as the extractant in dispersive liquid-liquid microextraction (DLLME) for the extraction and determination of vincristine in the plasma of children with leukemia prior to its anal. by high-performance liquid chromatog.-UV detection (HPLC-UV). Under optimal exptl. conditions, the method showed good linearity with a correlation coefficient (R2) of 0.9986 in the linear range of 0.06-300 μg L^-1, low limit of detection of 0.02 μg L^-1 and acceptable extraction efficiency (EE) of 88.4%. In the final stage of the study, this proposed technique was successfully applied to determine vincristine in real plasma, and the obtained results demonstrated the ability of the synthesized DES to extract drugs from biol. fluids.

N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3) belongs to organic chlorides. Organochlorines are organic compounds having multiple chlorine atoms. They were the first synthetic pesticides that were used in agriculture. They are resistant to most microbial and chemical degradations. Organochlorine compounds are lipophylic, meaning they are more soluble in fat than in water. This gives them a high tenancy to accumulate in the food chain (biomagnification).COA of Formula: C25H54ClN

Anaerobic treatment of glutamate-rich wastewater in a continuous UASB reactor: Effect of hydraulic retention time and methanogenic degradation pathway was written by Chen, Hong;Wei, Yanxiao;Xie, Chenglei;Wang, Hong;Chang, Sheng;Xiong, Ying;Du, Chunyan;Xiao, Benyi;Yu, Guanlong. And the article was included in Chemosphere in 2020.Safety of N-Methyl-N,N-dioctyloctan-1-aminium chloride The following contents are mentioned in the article:

To investigate the anaerobic treatment efficiency and degradation pathways of glutamate-rich wastewater under various hydraulic retention times (HRTs), a lab-scale upflow anaerobic sludge blanket (UASB) reactor was operated continuously for 180 days. Results showed that high COD (COD) removal efficiencies of 95.5%-96.5% were achieved at HRTs of 4.5 h-6 h with a maximum methane yield of 0.31 L-CH₄/g-COD. When the HRT was shortened to less than 3 h, the removal performance of the reactor declined. There also was an excessive accumulation of volatile fatty acids, which implies that an appropriately small HRT is applicable to the UASB reactor treating glutamate-rich wastewater. Methanogenic degradation of glutamate in the UASB reactor depended on the HRT applied, and the typical methane-producing capability of the sludge at an HRT of 3 h, in descending order, was acetate > glutamate > butyrate > H₂/CO₂ > valerate > propionate. Clostridium and Methanosaeta were predominant in the glutamate-degrading sludge. At least three degradation pathways most likely existed in the UASB reactor, and the pathway via 3-methlaspartate by Clostridium pascui was expected to be dominant. This study involved multiple reactions and reactants, such as N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3Safety of N-Methyl-N,N-dioctyloctan-1-aminium chloride).

A novel conjugated polymer PFCZ-IM containing 2-(thiophen-2-yl)-1H-benzo[d]imidazole units was synthesized and characterized. The basic photophys. properties of the polymer and its fluorescence recognition behaviors toward metal ions and amino acids were investigated. In the study of the response of metal ions, PFCZ-IM had high sensitivity to Fe³⁺, Ag⁺ and Cu²⁺, which significantly quenched the fluorescence of the polymer. The binding of the 2-(thiophen-2-yl)-1H-benzo[d]imidazole moiety to Cu²⁺ was investigated by d. functional theory calculation Interestingly, [PFCZ-IM-Cu²⁺] also exhibited outstanding characteristics of fluorescence ‘turn on’ in the presence of cysteine (Cys), as the interaction between Cu²⁺ and Cys caused the polymer to dissociate from the complex. In particular, addition of 30μmol L^-1 of Cys can increase the Cu²⁺-quenching fluorescence of PFCZ-IM by 34.8 times with short response time, demonstrating that [PFCZ-IM-Cu²⁺] has tremendous potential in the actual detection of Cys. This polymer is expected to be utilized for dual fluorescence detection of specific metal ions and Cys. 2021 Society of Industrial Chem.

Cleaner and lower-cost recovery and separation of samarium(III) and cobalt(II) from waste SmCo magnets can effectively alleviate supply risks of the strategic metals. Based on this goal, a family of renewable, low-cost, biocompatible, non-toxic fatty acid-based ionic liquids (FAILs), including [N1888][DA], [N1888][LA] and [N1888][PA] were synthesized and developed for the separation of Sm(III)/Co(II) from samarium-cobalt simulated solution The effect factors, i.e. equilibrium time, FAIL molar concentration, salting-out agent concentration and initial pH of aqueous solution were investigated. The extraction mechanism was proposed to be ion association by slope anal. and FT-IR. Under the optimized extraction conditions, a higher purity CoCl₂ (99.5%) product was obtained by a simple extraction-stripping-washing process with the consumption of Na₂C₂O₄ and NH₃·H₂O. The produced salty wastewater with lower concentration from the process could be recycled. Sm2O3 with a purity of 99% were obtained by roasting the Sm₂(C₂O₄)₃ at 800°C for two hours. The whole process was simple and sustainable, illustrating its potential for industrial applications.

Under the advocacy of the sustainable development concept, the extraction process and reaction mechanism for arsenic in alk. solution were studied with the aim of optimizing the alk. leaching process of high-arsenic copper smelting ash and promoting the recovery and harmlessness of arsenic. At 25°C, the extractant methyltrioctylammonium underwent 6-8 conversions of Na₂CO₃ solution with a concentration fraction of 12%, and the extraction capacity of thioarsenite was increased to 86.91%. Furthermore, at 25°C, at an O/A ratio of 1:1 and an phase contact time of 7 min, the thioarsenite stripping exceeded 99%, when using 4% H₂O₂ + saturated Na₂CO₃ solution as the stripping. Fourier transform IR spectroscopy, nuclear magnetic spectroscopy, UV spectroscopy, and other anal. methods were used to determine the mechanism of the extraction process. It was evident from our experiments that the CO^2-₃-type TOMAC and Na₂CO₃ solutions could be recycled and reused repeatedly. The overall process required simple materials and did not generate liquid waste. The technique involves a short process, with superior cycle performance, low cost, and high efficiency.

Tri alkyl ammonium hydrogen phthalate based ionic liquid has been explored for the efficient extraction of Zr and Hf from aqueous nitric acid solution During mass transfer Zr formed ZrL₂(NO₃)⁺ mono pos. species, which got exchanged with the single cations of the ionic liquid to maintain elec. neutrality in both phase. However, for Hf, the probable extracted species was ML(NO₃)₂⁺. The mass transfer processes were spontaneous, endothermic and driven by the entropic change in the systems. The D values for Zr were found to be more than that of the Hf due to more organophilicity of the complex. The significant changes in ligand functionalities: hydroxyl, carbonyl, -CO₂ of carboxyl, -OH of carboxyl on complexation with Zr⁴⁺ were evidenced by FTIR spectra. Till 200 kGy gamma exposure, the ionic liquid was found to be rigid. No appreciable modification in ligand functionalities were evidenced by FTIR. However, up to 15% reduction in extraction performance was observed The EDXRF spectra of the functionalized ionic liquid after processing of simulated high-level waste showed the presence of U, Zr, Fe, Mn, Rh, Ni, Zn and Y along with minute contamination of Ca and Na.

Synthetic dyes can cause many health problems, and their use as food additives is rigorously regulated worldwide. Two methods for the determination of synthetic dyes in food are described in this article. The visual qual. expression method was based on the extraction of synthetic dyes using a liquid anion exchanger (0.01 M solution of trioctylmethylammonium chloride in chloroform). Using this reagent, an optimal transition of 15 anionic synthetic dyes from the aqueous to the organic phase was achieved (R > 99.8%). It was applicable for testing food that must not contain synthetic dyes (wines, juices, etc.) in a very short time (5-10 min). In the case of coloring of the organic phase, identification and quantification was carried out using the HPLC-DAD method described. The rapid and simple method allows for simultaneous determination of 16 synthetic dyes from all food types. The LOD and LOQ ranged from 0.026 to 0.086μg mL^-1 and from 0.077 to 0.262μg mL^-1 resp., and recovery was 83.7-107.5%. Hypothesis: anionic synthetic dyes have hydrophobic properties, as a result they are retained on the non-polar stationary phase of the chromatog. column and are easily extracted from aqueous solutions by liquid anion exchangers.

Eutectic solvents with tuneable hydrophobicity: lipid dissolution and recovery was written by Lo, Calvin;Semerel, Jeltzlin;van den Berg, Corjan;Wijffels, Rene H.;Eppink, Michel H. M.. And the article was included in RSC Advances in 2021.Application of 5137-55-3 The following contents are mentioned in the article:

Despite the promising advantages of eutectic solvents, the application of these solvents as an extraction solvent is still limited due to the challenging product recovery. Previously, it was reported that lipids could be recovered from a hydrophobic eutectic solvent with the principle of switchable hydrophobicity. However, this method still involves addnl. chems., such as polymeric amines, water, and CO₂, which need to be removed later. In this study, we proposed a different approach by shifting the hydrophobicity spectrum of a semi-hydrophobic solvent. Made of hydrophilic imidazole and hydrophobic hexanoic acid, this combination showed tuneable hydrophobicity when the composition was changed, shown by the change of dipolarity (π*) scale from solvatochromic anal. At low imidazole content, the solvent was able to dissolve sunflower oil and algae oil, whereas, at high imidazole content, the solvent showed high affinity towards water. By adding imidazole to the solution of oil and the solvent, a phase split was induced between the oil-rich upper phase and the solvent-rich lower phase. With this approach, -75% of recovery efficiency was achieved for the two oils, with the purity of âˆ?00% for sunflower oil and 86% for algae oil.
