The objective of this work is to determine the conditions for sepa rating Co2+ and Cu2+ from Ni2+ in mixed acid(HCl-H2SO4) with N235(Alamine 336)as an extractant. The distribution coefficients of Ni2+
Co2+ and Cu2+ were measured under different conditions
and on the basis of the distribution coefficients obtained
equilibrium models for the three elements have been established by nonlinear least square method. These models were tested in a four-stage countercurrent extraction battery. The test results showed satisfactory agreement between models andmeasred.
