In this study, we conducted an experimental study and removal mechanism study for chloride ions remove from wastewater by a combination of CuSO4 and copper. Experiments studies have shown that CuSO4 combined with copper completely removes 95.31% of the chloride ions from wastewater with an initial chlorine concentration of 1300 mg/L within only 30 min at the optimum experimental conditions. The optimum experimental conditions are that CuSO4 concentration is 10 g/L, copper concentration is 8.6 g/L and the reaction temperature is 35 °C. The products such as CuCl and copper are characterized by XRD analyses. The CuSO4 added to the wastewater ionizes to form Cu2+, which reacts with the copper to form Cu+. Then a large amount of Cu+ reacts with chloride ions in the wastewater to produce CuCl precipitate. This leads to a decrease in the concentration of chlorine in the wastewater. This study demonstrates that the combination of CuSO4 and copper can quickly and efficiently remove chlorine from waste water.
