Abstract
En 中文
Industrial wastewaters are frequently contaminated with hazardous pollutants, including synthetic dyes and heavy metals. Adsorption has emerged as an efficient and cost-effective method for removing contaminants from wastewater, and advanced porous materials such as zeolitic imidazolate framework-8 (ZIF-8) have gained significant attention due to their high surface area. But pure ZIF-8 does not efficiently interact with different pollutants. To overcome this, ZIF-8 can be successfully combined with biopolymers and surface-active molecules. Such hybrid composites provide a promising approach for the simultaneous removal of dyes and heavy metal ions from wastewater. This study focused on the integration of aminated chitosan (AmCs with ZIF-8, followed by surface modification with cetyle triethyl ammonium bromide (CTAB), resulting in the development of a novel ZIF-8@AmCs/CTAB composite for the removal of Crystal violet (CV) dye and Cr(VI) metal ions from water.
