Synergistic extraction and separation of Co(II)/Ni(II) by solvent extraction technique using TIOA/TOPO as carriers

OpenAlex İngilizce

In this study, we investigated the selective and the synergistic cobalt extraction from acidic aqueous solutions by solvent extraction using tri-iso-octylamine (TIOA) and Tri-n-octyl phosphine oxide (TOPO) as carriers. The effective parameters on the extraction and the stripping of the cobalt were investigated, and optimum synergistic extraction and stripping conditions were identified. The cobalt extraction from aqueous Co/Ni solutions in various molar concentrations was examined in the optimum conditions to determine the synergism between TIOA and TOPO.
