摘要
Abstract
Removal of impurities(arsenic,antimony,bismuth)from copper electrolytic waste liquid by hydrogen sulfide was studied.The effects of the excess coefficient of hydrogen sulfide,reaction temperature,reaction time and stirring speed on the impurity removal of copper electrolytic waste liquid were investigated.The experimental conditions were further optimized by the response surface methodology,and the experiments were verified under these conditions.The results show that the optimal test conditions are as follows:the excess coefficient of hydrogen sulfide is 1.9,the reaction temperature is 68.1℃,the reaction time is 2.1 h,and the stirring speed is 524 r/min.Under the optimal conditions,the average impurity removal rate of copper electrolysis waste liquid can reach 94.2％.The optimized process parameters determined by the method are reliable and applicable,and will not affect the subsequent recovery of nickel elements.关键词
