摘要

Two solvent extraction systems for V (V) and Cr (VI) separation in leaching solution were investigated in order to select the suitable separation method for the disposing of chromium-bearing vanadium slag. The best/suitable system was determined by extraction yield (E-V,%) and the separation factor of V(V) and Cr(VI) ((V/Cr)). On the condition of 1:1 molar ratio of H+ to vanadium (V), the E-V values were 99.8% and 95.1%, while the (V/Cr) values were 546.58 and 29.53 using the two different systems, respectively. The extraction reactions for system 1 were determined by the slope method, and the chemical equilibrium constants were obtained.
