This study investigates the synthesis of SMS-Ti-Mn (SMS-Ti-Mn stands for spent mushroom substrate activated carbon-Ti-Mn) nanocomposites and their application in removing heavy metal antimony from water. In process mining smelting, concentration waste residue can still reach as high 80.5 mg/L. addition, soil electronic dismantling area is severely contaminated with antimony. short, enters environment various ways mining, manufacturing to final continuously migrates different environmental media, increasing exposure risk pollution. Single-factor experiments response surface methodology were employed determine optimal conditions, including adsorption time, pH, solid–liquid ratio. Material characterization was performed understand role nano-metals, kinetics analyzed using quasi-first-order kinetic model. The research results revealed that conditions removal an time 40 min, a pH 4, ratio 2:1 (mg/mL). Under these showed capacity 10.502 mg/g, which 5.8 times higher than iron coagulants, 11 manganese-modified carbon, 1.7 iron–manganese sludge adsorbents. Characterization enhanced functional groups (carbonyl, Ti=O, Mn=O), contributing improved adsorption. Kinetic analysis indicated physical dominant mechanism, regression model accurately predicted capacity. offer promising strategy treating antimony-contaminated water, strong potential practical applications water treatment. They decompose naturally after use, reduce secondary pollution, promote ecological balance. Secondly, agricultural treated be used fertilizer amendment improve quality sustainable development.
