Abstract

This research studies the effect of cadmium adsorption-desorption kinetics with different pyrolysis temperature biochar. The biochar which derived from rice husk at 300°C, 400°C, 500°C temperature for 30 minutes were added into Cd2+ solutions of 0.5 mg/L, 2.5 mg/L and 5 mg/L respectively. The optimal model of cadmium adsorption desorption kinetic behavior is the Level 1 dynamic equation. Indicates the increasing Cd2+ adsorption ability of biochar with pyrolysis temperature rising. Biochar also shortens adsorption process at relatively low Cd2+ initical concentrations.
