摘　　要：以Pb^(2+)为模板分子,以巯基壳聚糖为功能单体合成了交联巯基壳聚糖分子印迹聚合物,并研究其合成、吸附和洗脱条件,结果表明:合成的分子印迹聚合物抗酸性提高了,且保留了对Pb^(2+)良好的吸附性和识别选择性.This paper reported a molecular imprinted polymer of cross linking sulfhydryl chitosan with the Pb^2＋ as template numerator and the sulfhydryl chitosan as the single in function. The conditions of synthesis, absorption and desorption were studied .The results suggest that the molecular imprinted polymer of cross linking sulfhydryl chitosan by Pb^2＋ as template improves the acid resistance and has proper adsorption capactity and selectivity for Pb^2＋.
