摘要
以P507萃取分离镍钴后负载有机相为原料,使用连续化逆流萃取分离设备——混合澄清槽,分别以硫酸溶液、硫酸和硫酸钴混合溶液、硫酸钴溶液为洗涤剂研究了连续逆流洗镍工艺。结果显示,硫酸和硫酸钴混合溶液、纯硫酸钴溶液、硫酸溶液将有机相中镍浓度洗涤至小于5mg/L分别需要2级、3级和6~7级。
Nickel was washed from loaded organic phase of P507 by continuous countercurrent washing process in mixer-settler applying sulfuric acid solution(SAS),mixed solution of sulfuric acid and cobalt sulphate(MSSCS),and cobalt sulphate solution(CSS),respectively,as abstergent.The results show that nickel concentration in organic solution is 5 mg/L below after two-stage,three-stage and six to seven stage continuous countercurrent washing with SAS,MSSCS,and CSS respectively.
