The Review of Treatment of Copper Ion in Wastewater and Comparison Between Four Treatment

Abstract

This paper presents a comprehensive review of various methods used to remove copper ions from wastewater, highlighting their efficiency and feasibility. The main focus is on adsorption, ion flotation, membrane-based techniques, and electrochemical cells, with a particular emphasis on innovative approaches like the use of graphene oxide electrodes. The comparison and analysis section assesses each method’s removal efficiency, operational challenges, and costs, providing a critical perspective on their practical application in industrial settings.
