ANALYTICAL METHOD FOR THE ABSORPTIOMETRIC DETERMINATION OF CHROMIUM IN URANIUM OXIDES AND URANYL NITRATE CONCENTRATES

Technical Report ·
OSTI ID:4765935
The U oxides are dissolved in nitric acid, and the uranyl nitrate concentrates dissolved in water. Chromium is oxidized to dichromate and determined absorptiometrically as its diphenyl carbazide complex. The method as written is suitable for a concentration range of 0 to 160 ppm Cr. (J.R.D.)
