ANALYTICAL METHOD FOR THE ABSORPTIOMETRIC DETERMINATION OF COBALT IN ZIRCONIUM METAL AND ZIRCALOY

Technical Report · Thu Aug 27 00:00:00 EDT 1959

OSTI ID:4206544

Cobalt is determined absorptiometrically in the metal as the nitroso R- salt complex after complexing the zirconium wtth citrate and destruction of other nitroso R-salt complexes by boiling with nitric acid. Cobalt is extracted into chloroform from a hydrochloric acid solution of Zircaloy, as the potassium ethyl xanthate complex. The complex is destroyed by wet oxidation and the cobalt determined in the residue as a nitroso R-salt complex. The method is suitable for the determination of cobalt contents in the range 5 to 100 ppm. (auth)
