摘要: In this paper, Cd2+ was absorbed by the carboxylated bagasse hemicellulose, and the kinetics has been studied. The results show that absorption of the carboxylated bagasse hemicelluloses to ions Cd2+ can be well described by the pseudo second-order kinetics model. The theoretical value of the maximum absorption capacity q(e,cal) to ions Cd2+ was 29.41 mg/g. In addition, at temperature of 293 K, the pseudo second-order kinetics equation for ions Cd2+ adsorption was dq(t)/dt= 0.0433(29.41-qt)(2).
