摘要：In this study, cross-linked imprinted chitosan polymer (ICP) was synthetized from chitosan (CS), using tartaric acid-cadmium complex (TA-Cd) as template, and glutaraldehyde as the cross-linker. The parameters of influence of the sorption process were studied: solution pH, oscillating time and temperature. Results suggest that the most important factor affecting the effectiveness of sorption is pH and oscillating time. The second-order kinetics model was more suitable to describe the sorption kinetics on CS than the first-order kinetics model. Furthermore, the TA-Cd-ICP could be regenerated using 0.1 M HC1 solutions and could be reused for seven times with about 12.30% regeneration loss.
