采用悬浮聚合法制备了一种选择性三嗪除草剂的分子印迹合成聚合物受体，并将其应用于三嗪类除草剂西马津的专属性固相萃取，该过程涉及合成受体的反相操作以保留包括西马津在内的亲油性农用化合物在基质中，然后基于氢键的亲和分离表现出对西马津的选择性保留，洗脱其他不需要的化合物，固相萃取得到56倍的西马津浓缩液，回收率为91%。
A molecularly imprinted synthetic polymer receptor selective for triazine herbicides was prepared by suspension polymerization, and mas applied to the specific solid-phase extraction of simazine, one of the triazine herbicides, from mater, The procedure involves the reversed-phase mode operation of the synthetic receptor to retain lipophilic agrochemicals, including simazine, in mater, followed by affinity separation based on hydrogen bonding which exhibits selective retention of simazine, eluting the other undesired compounds, The solid-phase extraction yielded a 56 times concentrated simazine solution with a recovery rate of 91%.
