Abstract

This study evaluated the use of particles of molecularly imprinted and non-imprinted polymers (MIP and NIP) as a wastewater treatment method for endocrine disrupting compounds (EDCs). MIP and NIP remove EDCs through adsorption and therefore do not result in the formation of partially degraded products. The results show that both MIP and NIP particles are effective for removal of EDCs, and NIP have the advantage of not being as compound-specific as the MIP and hence can remove a diverse range of compounds including 17-β-estradiol (E2), atrazine, bisphenol A, and diethylstilbestrol. Removal of E2 from wastewater was also tested to determine the effectiveness of NIP in the presence of interfering substances and natural organic matter. Removal of E2 from wastewater samples was high and increased with increasing NIP. NIP represent an effective way of removing a wide variety of EDCs from wastewater.

摘要

本研究评估了使用分子印迹聚合物颗粒和非印迹聚合物颗粒（MIP和NIP）作为处理内分泌干扰化合物（EDC）废水的方法。MIP和NIP通过吸附去除EDC，因此不会导致部分降解产物的形成。结果表明，MIP和NIP颗粒对去除EDC均有效，且NIP具有不像MIP那样具有化合物特异性的优势，因此可以去除多种化合物，包括17-β-雌二醇（E2）、阿特拉津、双酚A和己烯雌酚。还测试了从废水中去除E2，以确定NIP在存在干扰物质和天然有机物的情况下的有效性。废水中E2的去除率很高，且随着NIP用量的增加而提高。NIP是从废水中去除多种EDC的有效方法。
