摘　　要： 用电位扫描法研究了EDTA溶液的阳极和阴极行为,确定了电解EDTA溶液时EDTA不分解的条件,提出了用电解法从稀土淋洗液中回收铜和EDTA。中槽试验结果表明,铜的回收率达98％,EDTA94％,EDTA纯度高达98％。 The anodic and cathodic actions in EDTA solution were studied with aid of potentiometer scanning method, and the condition that EDTA did not decompose was determined when electrolyzing EDTA solution and hence, recovery of copper and EDTA from rare-earth washing solution by electrolytic method was put forward. It was indicated in pilot electrolyzer that recovery ratio of copper was 98%,that of EDTA 94%, and purity of EDTA 98%
