Abstract

Pharmaceuticals and personal care products (PPCPs) are gaining attention due to their persistence in the environment. Therefore, the development of novel adsorbents to remove them is strongly anticipated. In this study, an improved dual ice-template assembly method had been used for the preparation of ZIF-67/QGO/SB-CS aerogel through ZIF-67, benzoquinone-modified graphene oxide (QGO), and sulfobetaine-modified chitosan (SB-CS) for the adsorption and removal of PPCPs in water. We reported for the first time that the chitosan composite aerogel has antifouling, bacterial filtration and oil-water separation abilities with excellent PPCPs adsorption performance and reusable, which would be a viable option for long-lasting adsorbents for PPCPs in water.

摘要

药品和个人护理产品(PPCPs)因其在环境中的持久性而受到关注。因此,强烈期望开发新型吸附剂来去除它们。在这项研究中,通过 ZIF-67、苯醌改性氧化石墨烯(QGO)和磺基甜菜碱改性壳聚糖(SB-CS),采用改进的双重冰模板组装方法制备了 ZIF-67/QGO/SB-CS 气凝胶,用于水中 PPCPs 的吸附和去除。我们首次报道了壳聚糖复合气凝胶具有抗污染、细菌过滤和油水分离能力,以及优异的 PPCPs 吸附性能和可重复使用性,这将是水中 PPCPs 长效吸附剂的一种可行选择。
