Improving the performance of Cr (VI) removal by electrochemical process using microbial cellulose/magnetic nanoparticles electrode

This study aimed to improve the performance of the electrochemical (EC) process for hexavalent chromium [Cr (VI)] removal using a metallic polymer anode. In fact, this anode had been prepared via the immobilized Fe3O4 as the magnetic nanoparticles on microbial cellulose (MC). Moreover, MC/Fe3O4 was modified and conducted by polypyrrole (PPy) and a sandwich panel of stainless steel. The conductive MC/Fe3O4 electrode was characterized by XRD, TGA, FE-SEM, and FTIR. In EC process of the Cr (VI) removal using the composite anode, factors such as chromium concentration, pH value, current density, energy consumption, as well as sludge production were also taken into account. The proposed EC reached 99.87% Cr (VI) removal efficiency using the current density of 5.3 mA/cm(2) within 20 min, pH of 3 +/- 0.5, and 10 mM sodium chloride (NaCl) as the supporting electrolyte. In addition, the composite electrode)SS_MC/Fe3O4@PPY (exhibited lower energy consumption (0.62 kWh/m(3)), as well as lower sludge production (0.018 kg/m(3)) compared with other EC processes. Moreover, results of the study revealed that reasons for these phenomena were Cr (VI) adsorption (18% in 30 min) on the composite electrode as well as Cr (VI) reduction on cathode (17% in 30 min). Another reason for the above phenomena could be attributed to EC caused by production of the metallic hydroxide flocks, which was released from stainless steel (90% in 30 min) and magnetic-microbial cellulose (26% in 30 min). Furthermore, MC/Fe3O4@PPy exhibited a good durability in the system. Therefore, the SS_MC/Fe3O4@PPY electrode could be utilized for long periods of time in the process. (C) 2020 Elsevier Ltd.

Vacuum-assisted diamine monomer distribution for synthesizing polyamide composite membranes by interfacial polymerization

Polyamide composite membranes are still required to promote their structure uniformity and desalination performance. Herein, a vacuum-assisted strategy was used to deal with this challenge by improving the distribution homogeneity of diamine monomer in porous substrates for typical interfacial polymerization. Laser scanning confocal microscope analyses demonstrate that the piperazine solution can be adsorbed in the microporous substrates with a very homogeneous and stable way. This uniform diamine distribution shows great advantages for synthesizing the selective layers of polyamide on the substrate surfaces via the interfacial polymerization of piperazine and trimesoyl chloride. The as-prepared polyamide layers with a circular size of 30 cm exhibit uniform structures including thickness less than 20 nm, cross-linking degree up to 100%, surface roughness lower than 20 nm and pore diameter about 0.41 nm. Therefore, the polyamide composite membranes present nanofiltration performances of ultrahigh rejection above 99.6% to Na2SO4 and high water permeability of 20 L/m(2) h bar. These membranes also show a promising selectivity for NaCl/Na2SO4 up to 196, which is higher than most of the commercial and the reported nanofiltration membranes in recent years.

Disaccharide anthocyanin delphinidin 3-O-sambubioside from Hibiscus sabdariffa L.: Candida antarctica lipase B-catalyzed fatty acid acylation and study of its color properties

Enzymatic lipophilization is an important process to extend the use of anthocyanins in lipidic media. In this work delphinidin 3-O-sambubioside (Dp3sam) isolated from Hibiscus sabdariffa L. flower was esterified with octanoic acid using Candida antarctica lipase B. The physical-chemical properties of the new lipophilic pigment were studied by UV-vis spectroscopy. Dp3sam with chloride, acetate and formate as counter ions were employed to study the lipophilization reaction. The hydrolysis of the reagent was avoided with a formate counter ion and the expected product was achieved with a noteworthy change of solubility. 1D and 2D NMR characterization of Dp3sam-C8 confirmed that the lipophilization took place at the primary alcohol of the glucoside moiety. Overall, the Dp3sam-C8 ester presents a stabilization of the quinoidal base (blue color) at neutral or moderate alkaline pH, which foresees a potential use of this pigment as a broad kind of industries on lipo-soluble formulations.

Effect of recycled aggregate treatment techniques on the durability of concrete: A comparative evaluation

The utilization of recycled aggregates (RA) in new construction has been promoted by many countries but the structural use of recycled aggregate concrete (RAC) is limited owing to inferior durability performance. The focus of this work is to study the effect of different RA treatment techniques on the durability properties of RAC. For this purpose, five different RA treatment methods such as immersion in acetic acid, immersion in acetic acid with rubbing, accelerated carbonation, immersion in acetic acid with accelerated carbonation and immersion in lime with accelerated carbonation are considered during the study. To investigate the effect of different RA treatment techniques on the durability properties of RAC, different durability tests such as water absorption, permeability, chloride ingress, acid attack and carbonation are performed. Improved resistance against water absorption, chloride penetration, carbonation, and acid attack is noticed for RAC having treated RA than RAC having untreated RA. Chloride migration coefficient values of RAC having RA treated through immersion in acetic acid with mechanical rubbing and immersion in lime with accelerated carbonation are observed very close to that for NAC. Moreover, scanning electron microscopy and mercury intrusion porosimetry results also show the enhanced microstructure, dense ITZ and improved porosity for RAC having treated RA than RAC having untreated RA, justifying the positive effect of RA treatment on the durability of RAC. Based on the results, immersion in lime with accelerated carbonation and immersion in acetic acid with rubbing techniques can be used to enhance the durability of RAC. Furthermore, regression models between physical properties of coarse aggregates and different mechanical and durability properties of concrete show that the porosity of coarse aggregates can be used to predict the mechanical and durability performance of concrete effectively, which may be a step towards the design guidelines of durable and eco-friendly concrete.

Rayleigh scattering and disorder-induced mixing of polarizations in amorphous solids at the nanoscale: 1-octyl-3-methylimidazolium chloride glass

Acousticlike excitations in topologically disordered media at mesocale/nanoscale present anomalous features with respect to the Debye’s theory. The so-called Rayleigh scattering manifests in a strong increase of the attenuation of the acousticlike excitations and a softening of the phase velocity with respect to its continuum limit value. Mean field models developed in the random media theory framework can successfully predict the occurrence, at the proper length scale, of Rayleigh scattering. The overall attenuation in the Rayleigh region is, however, underestimated. In the framework of random media theory we developed an analytical model, which permits a quantitative description of the acousticlike excitations in topological glasses in the whole first pseudo-Brillouin zone. The underestimation of the Rayleigh scattering is avoided and, importantly, the model allows to account also for the polarization properties of the acousticlike excitations. In a three-dimensional medium an acoustic wave is characterized by its phase velocity, intensity, and polarization. Rayleigh scattering emphasizes how the topological disorder affects the first two properties. The topological disorder is, however, expected to influence also the third one. In common with the Rayleigh scattering, hallmarks possibly related to the mixing of polarizations have been traced in different classes of amorphous solids at nanoscale. The quantitative theoretical approach developed permits to demonstrate how the mixing of polarizations generates a distinctive feature in the dynamic structure factor of amorphous solids. The modeling capability of the proposed mean field theory is tested on glassy 1-octyl-3-methylimidazolium chloride, whose spatial distribution of the elastic moduli is well assessed and can be experimentally characterized. Contrast between theoretical and experimental features for the selected glass reveals an excellent agreement. The mean field approach we present retains a certain degree of generality and can be possibly extended to different stochastic media or different wave fields.

Inhibition of K2SO4 on evaporation of KCl in combustion of herbaceous biomass

Several types of salts coexist in biomass and eutectic melting often occurs during combustion. The effect of eutectic melting on evaporation of salts is not well understood. The objective of this study is to investigate the interaction of two typical salts-potassium chloride (KCl) and potassium sulphate (K2SO4)-and the effect of eutectic melting on evaporation of KCl. Firstly, different potassium and their respective amounts in agro-stalks and their ashes were analyzed using X-ray fluorescence (XRF), X-Ray diffraction (XRD), and simultaneous thermogravimetric analyzer (STA). Then, the melting and evaporation behaviors of potassium salts were investigated using STA and evaporation rates of KCl in mixtures of KCl + K2SO4 as well as in agro-stalks ashes were calculated. Results show that KCl and K2SO4 (K3Na(SO4)(2)) are the main species of potassium, accountings for about 13% of agro-stalks ashes formed at low temperature. The evaporation rate of KCl is significantly inhibited by K2SO4 via decreasing vapor pressure of KCl due to eutectic melting. Its evaporation rate is approximately proportional to partial pressure of KCl in mixture of KCl + K2SO4, and the calculation using this partial pressure agrees well with experiment.

Dendrite-free Al recycling via electrodeposition using ionic liquid electrolytes: The effects of deposition temperature and cathode surface roughness

In this paper, the electrodeposition of Al from aluminum scrap alloys (A2020) on copper cathode substrates with varied surface roughness under different deposition temperatures was studied using low temperature AlCl3-1-butyl-3-methyl-imidazolium chloride (BMIC) ionic liquid electrolytes. The bulk electrodeposition of Al was carried out under a voltage of 1.5 V at a stirring rate of 120 rpm using a fixed ionic liquid electrolyte concentration (molar ratio AlCl3: BMIC = 2:1). The effects of deposition temperature (range from 80 degrees C to 140 degrees C) and surface roughness of Cu cathode substrates (polished by 320, 600, 800, 1200 grits SiC sandpapers and mirror polishing process) on the morphology of deposited Al, current density, current efficiency and energy consumption, were investigated. The Al deposits were characterized using scanning electron microscopy (SEM) with energy-dispersive X-ray spectroscopy (EDS), X-ray diffraction (XRD), profilometer, and electrochemical measurements for current density, current efficiency, and energy consumption. It is demonstrated that the deposition temperature and surface roughness of Cu electrodes play a critical role in the nucleation and growth of Al deposits. Higher deposition temperature promotes the diffusion and/or migration of Al2Cl7- ions and then enhances the current density and efficiency during the electrodeposition of Al. Smoother surface of Cu electrodes is preferred for the formation of dendrite-free Al deposits. Typically, on the mirror polished Cu electrode, no Al dendrite structure was observed, and only plate-like Al deposits were formed at the deposition temperature of 100 degrees C. Pure metallic Al was successfully deposited on Cu electrodes in AlCl3+BMIC ionic liquid electrolytes for all experiments with a current efficiency range from 72% to 99% and energy consumption of 4.6-6.3 kW h/kg Al.

Electrodeposition of Pd alloys from choline chloride/urea deep eutectic solvents

In this study, the electrodeposition of palladium alloys was investigated in a choline chloride/urea based deep eutectic solvent containing sulfosalicylic acid dihydrate as organic additive and Pd(II) + Ag(I), Pd(II) + Pt (II), or Pd(II) + Pt (II) + Ag(I) as metal components. The electrochemical behavior of the electrolytes was characterised by cyclic voltammetry. The electrodeposition processes require nucleation overpotential. Energy-dispersive X-ray data indicated that the layer thickness and composition of the produced Pd-Ag, Pd-Pt, and Pd-Pt-Ag films could be varied by changing the deposition mode. Additions of Ag(I) to the Pd and Pd-Pt electrolytes enhanced the overall metal deposition rate. Scanning electron micrographs of the electrodeposits showed that in general, the Pd alloys deposited by pulse current were nodular and relatively compact, whereas the films deposited by potentiostatic deposition were less dense and covered with dendrite-like and sharp-edged crystallites. Data collected from X-ray diffraction (XRD) experiments proved the existence of metallic alloys. (C) 2020 Elsevier B.V. All rights reserved.

Remote identification and ranking of Sodium in bulk liquid under high pressure condition

Laser Induced Breakdown Spectroscopy (LIBS) based spectral and temporal measurements are carried out to identify and rank the Sodium in bulk liquid under high pressure condition. The experiments are carried out by varying the incident laser irradiance (4 to 5 * 10(11) W/cm(2)), ambient pressure condition (1 to 8 atm) and stand-off collection distance (0.6 to 2 m). The concentration of Sodium Chloride (NaCl) in the sample solution is varied between 250 and 1500 ppm. From the spectral data, the Na I emission line (589 nm) is visualized for all experimentation condition. Emission due to singly ionized atom and doubly ionized atom are not observed, due to the requirement of high ionization energies. It is observed that the Na I (589 nm) peak intensity decreases with increase in ambient pressure condition, due to the plasma condensation effect. It is also observed that the Na I (589 nm) peak intensity increases with increase in incident laser irradiance. Temporal measurement based quantification of Sodium in bulk liquid is carried out. It is observed that the plasma emission time period (Na I at 589 nm) increases with increase in NaCl concentration. This is related to the re-excitation of neutral atoms (Na I) in the plasma state. In the stand-off distance analysis, it is observed that the plasma (Na I) emission peak intensity and time period of emission decreases with increase in stand-off collection distance. This might be due to the low coupling of plasma emission to the measurement system, at longer stand-off distances. The Na detection limit of about 10 ppm is achieved for a laser irradiance of 3 * 10(11) W/cm(2). The above specified detection limit is obtained for an ambient pressure condition of 1 atm and stand-off collection distance of 0.6 m. On a summary, remote LIBS with temporal measurement is highly suitable to identify and rank the Sodium concentration in bulk liquid under high pressure condition. However, the calibration of LIBS measurements at different experimental condition is required to utilize the instrument in real-time environment.
