Extraction of V(V) by LIX 63 and PC 88A was investigated from sulfate solutions under initial pH 1.2–6. Equilibrium pH had a profound effect on the extraction of V(V) by the two extractants. The extraction of V(V) by PC 88A occurred by a cationic exchange, while that by LIX 63 changed as the equilibrium pH increased. The cationic exchange reaction of VO2+ by LIX 63 occurred at pH < 2.5, while solvating reaction occurred in the equilibrium pH range of 2.5–5.4. The extraction reactions of V(V) by PC 88A and LIX 63 were identified by applying a slope method
