β-环糊精交联聚合物的合成及其在水处理中的应用

Synthesis of the Crosslinked Polymer of β-Cyclic Dextrin and Its Application in Water Treatment

以环氧氯丙烷为交联剂 ,在碱性介质中将 β-环糊精固载化 ,合成了不溶于水的 β-环糊精交联聚合物。同时考察了 β-环糊精交联聚合物对模拟水样中的微污染物 (无机重金属离子及有机酚类、胺类 )的吸附性能。实验结果表明 :β-环糊精交联聚合物对无机重金属离子 ( Pb2 + ,Cu2 + ,Cd2 + ,Zn2 + )及苯酚、苯胺的去除效果良好 ,前者的去除率达到 83.60 %以上 ,其中 Pb2 +的去除率高达 95 .62 % ,苯酚、苯胺的去除率达到 95

A water insoluble crosslinked polymer of β cyclic dextrin(β CD) with epichlorohydrin was synthesized and charactrized by IR spectra. The polymer not only kept the original characterization of β CD to form inclusion complexes,but also contained new C-O-C bonds which could coordinate to inorganic ions. The adsorption capabilities of the polymer for inorganic heavy metal ions(Pb 2+ , Cu 2+ , Cd 2+ , Zn 2+ ) and organic pollutants (phenol, phenylamine) were investigated and the results showed it had high removal ratio for the guests mentioned.
