摘要：
We studied vanadium(V) extraction by di-2-ethylhexylphosphoric acid (DEHPA) from 1.0-12.0 M sulfuric acid. Optimal extraction parameters were determined. IR, V-51 NMR, and electronic spectroscopy was used to determine the stoichiometry of the extracted complex and the reaction equation for vanadium(V) extraction by DEHPA. The equilibrium constant of vanadium(V) extraction by DEHPA was determined.
