Abstract: Faced to copper-nickel resources tense situation, we need to pay attention to the development of technical, and effectively improve the utilization rate of resources and reduce waste of resources; On the other hand, we can develop copper-nickel resources recovery and utilization of technology. Many countries are in-depth study of nickel-copper recycling technology.
This article established two kinds of methods for determination of nickel and copper: (1)Spectrophotometry (2) EDTA chemical titration.
Based on this method，we explored the process conditions of how to recycling copper and nickel from waste. We used M5640-kerosene-H2SO4 extraction system to recovery copper and nickel.
Keywords：Spectrophotometry; EDTA - lead nitrate titration; M5640;O/A
