Abstract

The extractive capacity of di(2-ethylhexyl)phosphoric and di(2,4,4-trimethylpentyl)phosphinic acids for vanadium(V) in its extraction from individual sulfuric acid solutions with the use of kerosene, a number of aliphatic alcohols, and octanone as diluents was studied. The most effective organic mixtures for extraction of vanadium(V) were determined in relation to the concentration of sulfuric acid.
