分子烙印聚合物吸附有机磷毒剂的研究

The Research of Adsorption of Organophosphorus Toxicants on Molecule Imprinting Polymers

以有机磷毒剂沙林为烙印分子，采用不同单体、交联剂及制孔剂制备了一系列分子烙印聚合物，从中筛选出了几种对沙林有很高吸附率（＞90％）的聚合物。发现这些聚合物对同沙林结构相近的其它有机磷毒剂如梭曼、塔崩及维爱克斯也有很好的吸附率。我们还考察了吸附率随时间变化的关系。

Molecule imprinting polymers (MIP) for sarin were made with different chemical composition.Adsorption of sarin and other organophosphorus toxicants on the MIPs were invesigated. It was found thatsome MIPs can adsorb most of sarin (＞90% ) in the solution. Organophosphorus toxicants with similarstruture of sarin can also be adsorbed by the MIPs. The relationship between adsorption rate andabsorption time was also investigated.
