Using graphene and its derivatives to remove copper ions from mine water

Abstract

China’s mining industry plays a significant role in the country’s economy but also poses environmental challenges, including pollution from heavy metals like copper. Traditional methods for removing copper ions from mine water have limitations in terms of effectiveness and cost-efficiency. This study explores the potential use of graphene and its derivatives as an alternative solution for adsorbing copper ions. Graphene oxide, in particular, shows promise due to its high surface area, chemical stability, and ease of production. The research findings demonstrate that graphene oxide has a high adsorption capacity for copper ions and can effectively remove them from mine water. This environmentally friendly approach offers a viable solution for mitigating copper pollution in China’s mining industry while contributing to sustainable mining practices and enhancing water quality management. By advancing these technologies and exploring low-cost manufacturing methods for carbon nanomaterials, this research addresses industrial pollution challenges not only in China but also globally.
