摘　　要：采用电渗析法对电镀镍回收液进行分离浓缩实验。实验表明,选用BJT离子交换膜,在溶液Ni2+初始浓度为2 g/L、电压值为7.5 V、浓缩室和淡化室流量均为8 L/h时,Ni2+浓缩到8.39 g/L,有机物的相对去除率达46.46%。电渗析法能实现镍回收液中镍离子与杂质的分离,达到净化回收液和浓缩镍离子的目的。Electrodialysis experiments were carried out to deal with simulated recovering water containing heavy nickel ion. The results show that BJT membranes have the highest separation rate. On the conditions that initial concentration was 2 g/L, voltage was 7.5 V, flows of concentrating and diluting compartment were both 8 L/h, the Ni2＋ concentration could reach 8.39 g/L and COD relative removal rate was 46.46 %. Electrodialysis process can achieve the separation of Ni2＋ and organic substance.
