摘　　要：通过一系列的反应先合成Schiff碱型大环化合物,然后以Schiff碱型大环化合物改性壳聚糖,合成得到的该种壳聚糖衍生物具有特殊结构与性能,这一活性产物对重金属如Pb2+具有良好的吸附与富集性能,与其他壳聚糖衍生物的吸附性能相比,该种Schiff碱型大环化合物改性的壳聚糖更加优越,吸附性能更好。A four-step reaction was reported in present paper to prepare an efficient chitosan,which was modified with Schiff base type macrocycle compound.The aimed compound was a special material for absorption of Pb^(2+).After characterization by Infrared Absorption Spectrometry and Polarography,the result were obtained that chitosan modified with Schiff base type macrocycles did have good adsorption behavior to Pb^(2+),and the adsorption capability was regarded as 5.6760mg/g.
