THE DETERMINATION OF IRON IN URANIUM DIOXIDE

Technical Report ·
OSTI ID:4226306

The sample is dissolved in nitric acid. Any insoluble matter is fused with potassium bisulfate, and the solution from the melt is added to the main solution. Sulfamic acid is added to suppress interference by nitrite. The iron is determined absorptiometrically by the formation of the thioglycollic iron complex in the presence of ammonium carbonate and ammonium citrate. The method is suitable for iron contents up to 350 ppm. The error except in the lowest ranges should not exceed plus or minus 5%. (auth)
