Evaluating the Effectiveness and Efficiency of a Graphene-Oxide Water Filtration System

Aaron Sarkar ABSTRACT Chemical contamination of drinking water is a major global health issue. While modern water filters treat some major contaminants, not all impurities can be filtered. Moreover, all filters are not cost-efficient and environmentally friendly. The current study aims to explore the effectiveness and efficiency of reduced graphene-oxide-coated sand as a water filter. …
