• A novel method for the solvent extraction separation of thallium(III) from associated elements is presented in this paper. Thallium(III) was quantitatively extracted at pH 4.0 from 0.1 M malonic acid with 0.08 M Amberlite LA-2 in xylene. Thallium was stripped from the organic phase with 1 M perchloric acid and was determined spectrophotometrically at 635 nm with malachite green. Thallium(III) was separated from zinc, cadmium, lead, iron, gallium and indium by process of selective extraction or selective stripping. It was possible to separate thallium (I) from thallium(III) in any proportion. It was also separated from the multicomponent mixture. The method was extended for the analysis of thallium in urine.
