A fast and selective method is proposed for solvent extraction of manganese with tributyl phosphate. It is possible to quantitatively extract manganese with 40% tributyl phosphate in xylene from solutions containing 1Mhydrochloric acid and 2.5Maluminum chloride as the salting-out agent. The metal from the organic phase is stripped with water and is determined photometrically as its complex with formaldoxime. The probable composition of the extractable species at 1Macidity is [MnCl2·3TBP]. It is possible to extract manganese in the presence of a twentyfold excess of common ions, but mercury, copper, iron, bismuth, and vanadium interfere. The standard deviation is ± 1.05%.
