The solvent extraction technology was applied to recover Cu

2+

and Ni

2+

from plating wastewater. Lix984N was chosen as the extractant due to its good extraction performance. The influence parameters were examined. The results show that the separation of Cu

2+

and Ni

2+

from sulphate medium can be realized by adjusting pH value with the help of Lix984N. For extracting Cu

2+

and Ni

2+

the optimal pH values are 4 and 10.5

and the maximal extraction percentages are 92.9% and 93.0%

respectively. With recovered Cu

2+

and Ni

2+

stripped in 170 g·L

the stripping percentages of Cu

2+

and Ni

2+

are 92.9% and 93.0%

respectively. This method is simple and can be used to recover Cu

2+

and Ni

2+

from plating wastewater. And a flow sheet for separation of Cu

2+

and Ni

2+

is presented.
