分子印迹技术在水中酞酸酯检测及处理的研究进展

Research progress of molecular imprinting technology on determination and removal of phthalates esters in water

邻苯二甲酸酯类物质(PAEs)是8种环境激素类物质之一,在水中的含量较低,但其产生的水环境危害一直备受关注。分子印迹聚合物(MIPs)因具有特异性的识别能力可作为选择性识别水中低浓度特定污染物的理想材料,因此在水环境中PAEs的检测和去除方面得到了较多的应用研究。概述了近年来国内外MIPs用于PAEs样品前处理、传感检测、吸附处理以及催化降解方面的应用研究,总结了MIPs选择性识别对PAEs检测及处理方法的影响并对未来研究方向进行了展望。

As one of eight environmental hormone substances,the water environmental hazards caused by phthalate esters(PAEs)has been paid much attention,even its concentration is low.Molecularly imprinted polymers(MIPs)exhibit specific recognition ability and can be used as ideal materials for the selective recognition of specific pollut⁃ants with low concentration,so MIPs have been widely used in the detection and removal of PAEs in water environ⁃ment.The related researches on MIPs for solid-phase(micro)extraction,sensing,adsorption removal and catalytic degradation of PAEs in recent years were introduced,and the influence of selective recognition of MIPs on the detec⁃tion and removal methods of PAEs and prospects the future research direction were summarized.
