THE ABSORPTIOMETRIC AND VOLUMETRIC DETERMINATIONS OF COMBINED NITROGEN IN BERYLLIUM METAL (MODIFIED ALLEN METHOD)

Technical Report ·
OSTI ID:4242366
The metal is dissolved in dilute sulfuric acid. The ammonias separated by distillation from alkaline solution, is determined absorptiometricallys using sodium phenate/sodium hypochlorite reagent for samples containing 10 to 4000 ppm combined nitrogen. Higher nitrogen contents are determined by absorbing the ammonia in standard acid and back titrating with standard alkali. The method has been used for pure metal flake containing 10 ppm to 2% combined nitrogen. (auth)
