Thorium is determined in uranium- thoriura, uranium--tungsten-thorium, and uranium -- titanium-thorium alloys by precipitation as the fluoride, using lanthanum as a carrier, followed by titration with EDTA. Eriochrome Cyanine RC is used as the indicator in the titration. ln 161 determinations of known solutions simulating the alloys with a thorium content of 0.1 to 3.0%, an average of 99.4% of the thorium was found. The relative standard deviation for individual values was 0.56% with no significant difference in the various synthetic solutions. (auth)
