Thorium--zirconium binary alloys are analyzed by complexometric procedures. For alloys containing more than 2O% thorium or 5% zirconium by weight, the sum of the constituents is obtained by a back titration procedure at pH 2.6 to 2.8 with bismuth nitrate using xylenol orange as indicator. Thorium is then masked with sulfate, and the liberated EDTA is titrated with bismuth at pH 1.2 to 1.3. For alloys containing less than 20% of thorium, thorium fluoride is precipitated on lanthanum fluoride to effect its separation before titration. For alloys containing less than 5% of zirconium, the zirconium is separated by precipitation with p-bromo-mandelic acid. (auth)
