Summary: This study investigates the use of anionic polyacrylamide hydrogels for the removal of cationic dye crystal violet from aqueous solutions. Batch adsorption studies show that the maximum adsorption capacity of the dye is 378 mg/g at an initial concentration of 300 mg/L, pH = 5, T = 298 K, and 0.039 g of the adsorbent. The adsorption mechanism follows the pseudo-second-order model, and the equilibrium adsorption follows the Langmuir model. Thermodynamic analysis suggests that the adsorption process is spontaneous and endothermic. Density functional theory (DFT), molecular dynamic (MD), and Monte-Carlo simulation studies were used to support the experimental findings.

Summary: In this study, the crucial role of Hydroxyapatite (HA) in the regeneration of hydroxyl radical (HO·) by a Fenton-like process for the degradation of Methyl Violet (MV) was demonstrated. The synthesized catalyst was characterized using various techniques, and the effects of pH, H2O2 concentration, catalyst dose, and reaction temperature on the degradation process were investigated. The main active species for MV degradation was found to be HO· formed through the reaction between HA and H2O2. Moreover, electrochemical impedance spectroscopy (EIS) showed an increase in electron charge transfer across HA in the presence of H2O2 and MV/H2O2.

Summary: In this study, PVDF-based anion-exchange membranes were designed to selectively separate nitrate from chloride. Experimental data showed that increasing the concentration of PVDF enhanced nitrate transport but also increased the membrane electrical resistance. The selectivity of nitrate was found to be independent of the membrane thickness and mainly driven by the increased affinity between the anion and the membrane.

Summary: This study focuses on the modification of a commercially available polyamide thin-film composite membrane with a zwitterionic material to enhance its fouling resistance. The modified membrane shows improved salt rejection and reduced permeability compared to the pristine membrane. Fouling tests demonstrate that the modified membrane has a lower fouling ratio and higher recovery ratio. The enhanced antifouling characteristics are attributed to the improved hydrophilicity resulting from the zwitterionic brushes and the salting-in effect.

Summary: To meet the huge demand for lithium resources, there is an urgent need to develop a new efficient technology for lithium recovery from salt-lake brines. In this study, a selective membrane capacitive deionization system is reported, which achieves high lithium recovery capacity and rate through the use of materials with efficient intercalated pseudo-capacitance and a high specific area porous carbon. The use of a modified thin-coated membrane allows for selective Li+ recovery, and adjusting the concentrations of Li+ and Mg2+ in the feed solution enables higher Li+/Mg2+ selectivity.

Summary: In this study, a novel polydopamine-functionalized lignin-containing pulp foam evaporator with high-efficiency desalination and multi-contaminant adsorption capabilities was designed. The foam evaporator showed excellent light absorption, water absorption, thermal conductivity, and chelation abilities, allowing for solar evaporation and contaminant adsorption synergistically. It also exhibited potential applications in metal ion concentration and contaminated seawater treatments, and demonstrated superior biodegradability compared to poly-styrene foam. This foam material holds promise for developing multifunctional photo-thermal systems for solar-driven water purification.
