【摘要】 采用氢氧化钙对化学镀镍废液进行沉淀处理，镍的去除率可达99％以上，亚磷酸根和硫酸根的去除率可达82％和18％。在弱酸性条件下用氯化钙再生镀液，亚磷酸根及硫酸根的去除率可达83％和55－70％，而镍的损失不超过14％。更多还原

【Abstract】 The spent of electroless Nickel coaling solutionwere treated by adding cadium hydroxide, the removal ofnickel was great than 99 %. Meanwhile, 80 % of phosphateanions and 18 % of sulphate anions were removed. AddingCadium Chloride to regenerating the solution under weakly acidic condition, the removal reached 83 % for phosphate anions and 55 - 70 % for sulphate anions, and the loss ofnickel were less than 14 %.更多还原
