The highly efficient removal of mercury metal ions at a higher pH (basic media) is barely reported in the literature. In this study, we developed novel adsorbent by blending chitosan with guar gum, designed to effectively remove from basic media stabilizing them gold (Au3⁺) solution. FTIR confirmed compatibility and gum through hydrogen bonding. morphology blend exhibited an amorphous porous structure. A mesoporous structure surface area, volume, diameter 11.843 (m2/g), 0.184 (cm2/g), 17.072 nm, respectively, was BET. adsorption behavior analyzed using isotherms kinetics models, which best fitted pseudo-second-order kinetic model Freundlich isotherm model, respectively. shown be excellent candidate for water, efficiency 92% 12 60 min maximum capacity 370.37 (mg/g).
