Silicon-substituted carbonate hydroxylapatite (Si-CHAP) was successfully synthesized by hydrothermal method with abandoned eggshell as raw material, and characterized by FT-IR. Its adsorption equilibrium, kinetics and thermodynamics to Mn2+ were investigated under different temperatures. The results showed that the adsorption equilibrium well fitted to Langmuir equation, the maximum adsorption amount for Mn2+ onto Si-CHAP was 38.91 at 20, 41.49 at 30 and 43.10 mg/g at 40°C. The adsorption kinetics accorded with the pseudo second order kinetic ...
