title: Solvent extraction of manganese with thenoyltrifluoracetone.
abstract: The formula of the manganese-TTA complex extracted with xylene from 0.5M sulphuric acid solution containing sodium bromate is MnT(3) where HT is the enol form of thenoyltrifluoracetone, TTA. The formula of the manganese-TTA complex extracted from slightly acid solution (pH 4-5) with acetone-benzene mixture is MnT(2). The extraction constants of the MnT(2) and MnT(3) systems are calculated to be 3 x 10(-7) and 1 x 10(3), respectively. The distribution ratios of TTA under various extraction conditions are given.
