Abstract
AbstractThis study presents the preparation and application of a 5-sulfosalicylic acid-loaded anion-exchange resin to remove Be2+ from aqueous solutions. Optimization efforts focused on critical parameters, including resin dosage, initial solution pH, and the influence of interfering ions. Results indicate an optimal resin dose of 0.3 g and a working pH of ≥ 4.0 for maximal Be2+ removal efficiency. Kinetic analysis reveals rapid removal kinetics, with 99% removal achieved within 45 min. Notably, the resin exhibits remarkable selectivity, maintaining consistent removal rates for Be2+ even in the presence of common interfering ions such as Na+, K+, Ca2+, Mg2+, and Fe2+. Sorption isotherms fitting the Langmuir model further support the resin's effectiveness in Be2+ removal. Thermodynamic evaluation suggests the removal process is spontaneous (∆G° < 0) and endothermic (∆H° > 0), indicating favorable energetics. Crucially, the Be-loaded resin is easily regenerated using 0.1 M HCl, enhancing its practical applicability. These results highlight the effectiveness and potency of the prepared resin in Be2+ removal, suggesting promising solutions for addressing environmental contamination.
