摘要： 以壳聚糖(CTS)为基体, 二丁基锡(DBT)为模板, 采用分子印迹技术制备了在空间结构和结合位点上与DBT匹配的分子印迹聚合物(DBT-MIPs). 研究了该分子印迹聚合物的合成条件、对DBT的吸附性能和选择识别能力, 并对其结构进行了表征. 结果表明, 所合成的DBT-MIPs对DBT具有良好的吸附和选择识别能力, 最大吸附量为178.6 μg/g.

Abstract: By using dibutyltin(DBT) as the template molecule, chitosan as the functional monomer and glutaraldehyde as the cross-linking monomer, dibutyltin molecularly imprinted polymers(DBT-MIPs) were synthesized by the molecular imprinting technology. In this paper, the structure of DBT-MIPs was characterized with scanning electronic microscope, and the synthesis conditions of DBT-MIPs, the adsorption properties and selective recognition of DBT-MIPs for DBT were also studied. The experimental results show that DBT-MIPs has a high adsorption capacity and good selective recognition for DBT, and the maximum adsorption capacity of DBT-MIPs is 178.6 μg/g.
