The nitration and degradation of copper extractants in the nitric acid system were studied . The effect of nitrate concentration ,pH of feed solution ,temperature of extraction system and modifiers on the nitration of the copper extractants were examined .Two anti-nitration reagents were developed and their anti-nitration ability in the nitric acid system was investigated .The results show that the anti-nitration reagents can significantly enhance the anti-nitration ability of the copper extractants .The measures for decreasing the nitration of the copper extractants are suggested ,and a good way for hydrometallurgical plants to select the appropriate copper extractants and reduce the nitration of the extractants are pointed out .
