In this study, an improved method was used to prepare ZIF-67/QGO/SB-CS aerogel for the removal of PPCPs in water. The aerogel exhibited antifouling, bacterial filtration, and oil-water separation abilities, with excellent adsorption performance.
Pharmaceuticals and personal care products (PPCPs) are gaining attention due to their persistence in the envi-ronment. 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 aer-ogel 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.
