Summary: In this study, Cu2+ was doped into ZnAl hydrotalcite to enhance its phosphate adsorption capacity. The Cu2+ doping increased the inter-layer spacing and specific surface area of the adsorbent. The optimal doping amount was found to be 1% of the total metal molarity. The resulting ZnAlCu layered trimetallic oxide exhibited significantly improved phosphate adsorption performance compared to ZnAl hydrotalcite and ZnAlCu ternary hydrotalcite.

Summary: This study investigated the use of magnetic Zn-Al layered double hydroxides (MZA) for the adsorption of malachite green (MG) and Congo red (CR) in aqueous solution. MZA was successfully synthesized and characterized. Batch experiments were conducted to determine the effect of various adsorption parameters on the adsorption capacity of MG and CR by MZA. Kinetics, isotherm, and thermodynamics analysis revealed the adsorption behavior of MG and CR on MZA. The results suggest that MZA is a potential adsorbent for purifying wastewater containing MG and CR.
