The extraction of vanadium(V) from hydrochloric acid solution by tri-<I>n</I>-octylmethylammonium chloride (TOMAC) was studied, employing benzene and chloroform as diluents with differing solvating characteristics to the extractant. The reduction of vanadium(V) to vanadium(IV) in the acid solution and the association of the extractant in the organic phase are taken into consideration. The vanadium extraction is assumed to occur via monomeric species of TOMAC in competition with the formation of acid complex in both diluent systems. Extraction equilibrium formulations that can express the vanadium(V) extraction over a wide range of metal loading of the extractant in both diluent systems are presented.
