摘要：

Extractions of vanadium(V) from diluted and concentrated nitric acid solutions by di(2-ethylhexyl)phosphoric acid (HDE-HP) in various solvents have been studied. From diluted nitric solutions, V(V) is extracted by dimeric (HDE-HP)2 in non polar solvents such as kerosene and by monomeric HDE-HP in polar solvents such as n-butanol. From concentrated nitric acid solutions, the extracted complex of vanadium involves nitrates group participation. © 1979.
