Abstract:
The influencing factors and kinetics of copper ions removal from aqueous solution by zero-valent iron (ZVI) was investigated, the mechanism of Cu2+ removal was analyzed using X-ray diffraction (XRD). The experimental results showed that ZVI had been turned out to be an effective tool for the removal of Cu2+ from aqueous solution. More than 99% of Cu2+ could be removed at an initial concentration of 300 mg/L by ZVI at the dosage of 1 g/L. The removal of Cu2+ in the first 30 min could be described by the first-order kinetic model with high correlation coefficient. The XRD analysis suggested that the mechanism for Cu2+ removal was mainly based on the redox reaction, which resulted in the formation of Cu2O qand CuO as the main reduced products of Cu2+.
