Separation of Cobalt and Nickel from Wastewater by P₂₀₄ Microemulsion Saponified

Abstract:

The separation process of cobalt and nickel using microemulsion system saponified with P204 as extracting agent was studied. The influence of initial concentration, the concentration of P204, initial pH, the extracting time and the concentration of cobalt and nickel on separation coefficient were also studied. Experimental results show that the saponification microemulsion system using P204 as extractant is thermodynamic stable, and it can separate cobalt and nickel better. The optimum conditions were achieved as: the initial concentration is 0.05 mol/L, pH is 2, the concentration of P204 is 8%, extraction time is 10 minutes, the volume ratio of organic phase to water phase is 2:1.
