水溶性β-环糊精交联聚合物的合成及其络合性能研究

Synthesis and Coordination of Water Soluble Cross Linked Polymer of β-CD

以环氧氯丙烷为交联剂 ,在碱性介质中合成水溶性 β 环糊精交联聚合物。考察了水溶性 β 环糊精交联聚合物对重金属离子的络合性能。实验结果表明 :β 环糊精交联聚合物对重金属离子的吸附性能强。

Water soluble cross linked polymer of β-CD with epichlorohydrin not only kept the original characterization of β-CD to form inclusion complexes, but also could coordinate to inorganic ions due to introduction of new C-O-C bonds. Its structure was characterized by IR spectra. The adsorption capabilities for inorganic heavy metal ions(Cd 2+,Cu 2+,Pb 2+,Zn 2+) were investigated. The results showed that the cross linked polymer had a good coordination capability to the heavy metal ions.
