Synthetic polymer receptors selective for atrazine have been prepared by molecular imprinting using trialkylmelamines as template molecules in place of atrazine. Trialkylmelamines were shown to be useful as templates for introducing affinity for atrazine into ethylene glycol dimethacrylate-methacrylic acid copolymers. The polymers showed the selective binding capacity for triazine herbicides including atrazine, whereas agrochemicals in other categories were not adsorbed to the imprinted polymers. The group selectivity demonstrated was comparable with that of the original atrazine imprinted polymers. Use of the nonagrochemical template molecules as a substitution to atrazine has made it possible to synthesize herbicide-receptor polymers free from troubles caused by analyte contaminants, which are desired for analytical applications.
通过分子印迹技术,以三烷基三聚氰胺作为模板分子替代莠去津,制备了对莠去津具有选择性的合成聚合物受体。结果表明,三烷基三聚氰胺可用作模板,将对莠去津的亲和力引入乙二醇二甲基丙烯酸酯 - 甲基丙烯酸共聚物中。该聚合物对包括莠去津在内的三嗪类除草剂表现出选择性结合能力,而其他类别的农用化学品不会吸附到印迹聚合物上。所表现出的基团选择性与原始莠去津印迹聚合物相当。使用非农用化学品模板分子替代莠去津,使得合成无分析物污染物引起麻烦的除草剂受体聚合物成为可能,这对于分析应用是非常理想的。
