THE DETERMINATION OF NIOBIUM IN URANIUM-NIOBIUM ALLOYS

Authors: Bryson, T. C.; Goward, G. W.; Hartmann, M. D.;

THE DETERMINATION OF NIOBIUM IN URANIUM-NIOBIUM ALLOYS

Abstract

Niobium is determined as the peroxy complex in concentrated sulfuric acid by photometric measurement at 360 m mu . Uranium interference is cancelled by using a solution of the sample for reference in the photometric measurement. The method covers the determination of niobium in uranium --niobium alloys made from pure melting stock. Molybdenum interferes and must be removed if present. Zirconium does not interfere. The calibration curve covers a concentration range from 0.2 to 5.0 mg. (auth)
