Separation of nickel from cobalt using electrodialysis in the presence of EDTA
TL;DR: In this article, the authors determined the optimum conditions for the removal of nickel from cobalt solutions by electrodialysis exploiting the greater stability of the EDTA complex with nickel, but there is a compromise between cobalt purity and the percentage of cobalt transferred to the catholyte chamber for recovery.

Studies on the applicability of artificial neural network (ANN) in emulsion liquid membranes
TL;DR: In this paper, an artificial neural network (ANN) model of emulsion liquid membrane (ELM) process is proposed which is able to predict solute concentration in feed during extraction operation and ultimate % extraction at different initial solute concentrations in feed phase, internal reagent concentration, treat ratio, volume fraction of internal aqueous phase in emulsion and time.
