Eco-friendly reduced graphene oxide@potash alum-based composite membranes for efficient separation of dyes and selective removal of contaminants from wastewater
Abstract
, Congo Red, Eosin Y, and Rose Bengal, achieving rejections of up to 99.9%, 99.8%, and 99.2%, respectively. Besides these, the membrane also shows great rejection for cationic dyes, such as 99.0%, 99.6%, and 99.2% for methylene blue, methyl green, and methyl violet, respectively. In addition, the as-prepared membrane maintains its performance for over 15 days under aqueous conditions, even after sonication. This study underscores the effectiveness of the rGO@PA hybrid membranes for wastewater treatment applications, offering a robust, cost-effective solution for environmental remediation applications.
