THE DETERMINATION OF NITROGEN IN VANADIUM METAL

Technical Report · Tue Apr 17 04:00:00 EST 1956

OSTI ID:4289245

The metal is dissolved in hot 9M sulfanric acid assisted by the addition of hydrogen peroxide. The ammonia, separnted by distillation from alkaline solution, is determined absorptiometrically using either sodium phenate/sodium hypochlorite reagent for samples containing 5 to 90 ppm combined nitrogen or Nessler's reagent for samples cortaining 90 ppm to 2% combined nitrogen. In the 5 to 90 ppm range results show a negative bias of about 5% wtth a coefficient of variation of plus or minus 5% or better. At the 300 to 600 ppm levels the results show a quaniitative recovery with a coefficient of variation of about plus or minus 3%. (auth)
