ANALYTICAL METHOD FOR THE ABSORPTIOMETRIC DETERMINATION OF CHROMIUM IN ZIRCONIUM METAL AND ZIRCONIUM TETRACHLORIDE

Technical Report ·
OSTI ID:4217788
The zirconium metal and zirconium tetrachlomde are dissolved in sulfuric acid. Chloride ions are removed and the chromium oxidized with ammonium persulfate in the presence of silver nitrate. The chromium is complexed with diphenylcarbazide and the absorbancy measured using a Spekker absorptiometer. The method is suitable for up to 80 mu g of chromium in the aliquot of sample taken.
