| Abstract: | In this paper,copper slag method has been applied to decline chlorination concentration in Zinc electrolytic solution and some concerned factors have been studied through orthogonal experiment.The experimental results show that the optimal technology conditions for this method would be: the molar ratio of Copper of copper slag and Cl-is 1.25∶1,the molar ratio of CuSO4 ·5H2O and Cl-is 0.6∶1,the reaction temperature is 70 ℃ and the reaction time is 3 h,the primary dechlorine rate reaches 85% and above.A second-time dechlorine will enable the chlorine content to drop to 100 mg/L. |
