Abstract
In this paper, simultaneous recovery and separation of copper and nickel from ammoniacal medium through double supportedliquid membranes containingN902 as carrier were investigated. The results show that copper was continuously transported across double membranes, but nickel only was transported throughone of them. Therefore, more than92.4% of nickel and 94.0% of copperinthe mixed feed phase wereseparated into the twodifferent strip phaseswitha transporttime of 30 hoursunder the conditions:6 g/L and 180 g/L H2SO4 solutions as two different strip phases, 100 mg/L each of two metals dissolved in 2.0 mol/L total ammoniacal solution as the feed phase, and 25 vol.%N902 as the carrier in two membranes.
