A study is given on the extraction of trivalent antimony halides by nonpolar solvents, nitrobenzene, Amberlite LA-2 from sulphuric and orthophosphoric acids. These two acids, because of their dehydration action, were found to have an enhancing effect on the extraction of Sb(III) halides. Extraction by nonpolar solvents and nitrobenzene was also studied as a function of the antimony concentration.
