摘要：

In this paper, Pb2+ 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 Pb2+ can be well described by the pseudo second-order kinetics model. The theoretical value of the maximum absorption capacity q(e,cal) to ions Pb2+ was 59.52 mg/g. In addition, at temperature of 293 K, the pseudo second-order kinetics equation for ions Pb2+ adsorption was dq(t)/dt= 0.0237 (59.52-qt) (2).
