The efficiency and effects of using Bisphenol A-molecularly imprinted polymeric microspheres (MIPMs) to remove phenolic estrogens from different sources of water were evaluated. MIPMs prepared by precipitation polymerization removed a group of phenolic estrogens from different kinds of water selectively and effectively. The highest removal efficiency was observed at pH=5. Fifty millimoles per litre ions or 10mg/L humid acid improved removal efficiency. MIPMs were more suitable to remove trace estrogens in large volume than high concentration of estrogens in small volume. The removal efficiency of spiked tap water, lake water and river water were better than that of distilled water. Hundred milligrams of MIPMs had higher removal selectivity and efficiency than those of 100mg or 300mg activated carbons. Moreover, MIPMs can be re-used for at least 30 times without losing any removal efficiency. MIPMs provided a selective, simple, reliable and practicable solution to remove trace phenolic estrogens from different sources of water.
评估了使用双酚A分子印迹聚合物微球(MIPMs)从不同水源中去除酚类雌激素的效率和效果。通过沉淀聚合法制备的MIPMs能够选择性且有效地从不同类型的水中去除一组酚类雌激素。在pH = 5时观察到最高去除效率。每升50毫摩尔的离子或10毫克/升的腐殖酸可提高去除效率。MIPMs更适合去除大量水中的痕量雌激素,而非小体积高浓度的雌激素。加标自来水、湖水和河水中的去除效率优于蒸馏水。100毫克的MIPMs比100毫克或300毫克的活性炭具有更高的去除选择性和效率。此外,MIPMs可重复使用至少30次而不损失任何去除效率。MIPMs为从不同水源中去除痕量酚类雌激素提供了一种选择性、简单、可靠且可行的解决方案。
