摘　　要：将“亲水-疏水”结构引入胶体晶体中,探讨新型光学检测材料——富集胶体晶体测定水质中阿特拉津残留的可行性。以阿特拉津为模板分子,由疏水胶体颗粒与亲水凝胶制备富集胶体晶体。富集胶体晶体对阿特拉津残留最低检测浓度为2 ng/mL,并展现出较高的检测特异性,在实际饮用水样品中阿特拉津加标回收率在89.0%~105.5%之间,具有良好的应用价值。By introduction of the“hydrophilic-hydrophobic”structure into colloidal crystals,the new optical materials,enrichment colloidal crystals,were developed for the determination of atrazine residue in drinking water samples.The enrichment colloidal crystals were composed of the hydrophobic colloidal particles and hydrophilic gel using atrazine as the template molecules.The enrichment colloidal crystals had a minimum detection concentration of 2 ng/mL for atrazine residues,and showed highly detection specificity.The recovery rate of atrazine in actual drinking water samples was 89.0%-105.5%,showing great applications future.
