Numerical simulation of separation of cobalt and nickel using hollow fiber supported liquid membrane (HFSLM)

초록

The selective separation of cobalt ion from a feed solution containing cobalt and nickel ions using a hollow fiber supported liquid membrane (HFSLM) was analyzed to evaluate the design parameters. A mathematical model for the simultaneous permeation of cobalt and nickel ions was developed and model equations were solved using the orthogonal collocation technique. The prediction by the model was in good agreement with the experimental data obtained using the HFSLM. The effect of various operating conditions, such as pH in the feed phase, carrier composition, module thickness, and module length, was analyzed. The optimum operating conditions with the highest flux and separation factor of cobalt ion were determined based on the simulation results.
