Thorium is separated from uranium, titanium, and tungsten by precipitation as fluoride. The precipitate is ignited to oxide, dissolved in nitric acid, evaporated with perchloric acid, neutralized to a pH between 2.0 and 2.5, and titrated with the disodium salt of ethylenediamine tetraacetic acid, using Eriochrome Cyanine as indicator. If less than 30 mg of thorium is present, lanthanum is added as a carrier. (auth)
