Summary: This study investigated the impact of operational and water quality parameters on brackish water decontamination using a batch electrodialysis (ED) system. The results showed the significance of ionic characteristics in ED, with nitrate concentrations satisfying guideline threshold in all experiments. Lowest arsenic(V) concentration was 35 mu g/L at the highest electric potential, 25 V, demonstrating the potential of ED in environmentally friendly processes.

Summary: In recent times, the removal of arsenic from wastewater has become crucial due to its persistence and bioaccumulation, which cause serious health and environmental issues. The electrodeionization (EDI) technique, utilizing hybrid electrodialysis/ion exchange, is reviewed as a sustainable approach for detoxifying wastewater by eliminating toxic arsenic. The EDI process employs anion/cation exchange resins that are efficiently regenerated by an electric current, leading to a significant reduction in water ions. The study discusses module configuration, performance optimization, ion separation mechanism, and recent advances in utilizing EDI for the removal/recovery of toxic arsenic.

Summary: This study presents the ecofriendly synthesis of magnetite nanoparticles (Fe3O4 NPs)-immobilized halloysite nanotube (HNT) composite (Fe3O4@ HNT) for remediating arsenate [As(V)] from water. Fe3O4@HNT was easily separable by an external magnet and showed excellent efficiency in removing As(V) from groundwater. The material was also cost-effective, reusable, and biocompatible, making it a prospective composite for the sustainable eradication of arsenic and other metallic toxicants from wastewater.

Summary: This paper reports on the performance of cross-linked amidoxime hosted into mesoporous silica (AMOX) for the removal of As(III) and As(V). The optimal pH for sorption of As(III) and As(V) were found to be pH 8 and pH 5, respectively. The kinetic model and isotherm analysis showed good fit with the experimental data. Thermodynamic parameters revealed that the adsorption process of As(III) and As(V) was spontaneous and endothermic on all AMOX sorbents. Furthermore, the spent AMOX sorbents could be easily regenerated and reused multiple times. The adverse effect of co-existing inorganic anions on the adsorption of As(III) and As(V) was also evaluated.

Summary: A novel high-efficiency vermiculite/zinc hexacyanoferrate (II) (VMT/ZnHCF) composite adsorbent was prepared to solve the problems of low adsorption capacity, complex preparation, and difficult recovery for reported cesium ion adsorbents. The composite exhibited a maximum Cs+ adsorption capacity of 378.79 mg/g, which was significantly higher than other absorbents. The Cs+ adsorption mechanism was revealed to be synergistically achieved through the ion exchange of Na+ in vermiculite interlayers and Zn2+ in zinc hexacyanoferrate (II) lattices, as analyzed by ion exchange experiments and characterization techniques.

Summary: In this study, hexagonal boron nitride (h-BN) was synthesized and used as an efficient sorbent for the uptake of Cd2+ ions. The kinetics and sorption studies showed that the process of Cd2+ sorption remained endothermic, and the Ho's model was found to best interpret the adsorption kinetic data. The physicochemical properties of h-BN were characterized before and after adsorption, showing its effectiveness as an adsorbent for Cd2+ ions in aqueous media.

Summary: In this study, the removal of arsenic and selenium from brackish water using a batch electrodialysis system was investigated. The results showed that the removal of these elements was influenced by pH and salinity, with higher concentrations leading to higher removal rates. Electromigration transport was found to be the dominant mechanism, and the ionic characteristics played a key role in the removal process. Real contaminated groundwater samples also demonstrated the potential of electrodialysis for selective removal of more mobile ions.

Summary: Complex solid residuals can form during the electrocoagulation of arsenic from aqueous media based on the characteristics of the electrochemical system and cooccurring processes. The composition and behaviors of these residuals were studied in this research, revealing the formation of different minerals depending on the pH of the solution. The study also showed that adsorption and chemical precipitation occurred simultaneously during the electrocoagulation of arsenic in aqueous media.
