The Determination of Small Amounts of Thorium in the Presence of Uranium, Titanium, and Tungsten

Thorium is determined in uranium alloys by means of a fluoride separation followed by a complexometric titration. A nitric of hydrochloric acid solution of the alloy is neutralized to a pH of 2.0 to 3.0 and the thorium precipitated as thorium fluoride by the addition of hydrofluoric acid and ammonium fluoride using lanthanum as a carrier.
