Abstract

The paper describes a method for the determination of uranium content in enriched U−Al alloys. The mass-spectrometric isotope dilution method was proposed and verified for the determination of uranium in these materials. A solution of natural uranylnitrate, prepared by dissolution of standard reference material NBS-U-960, was used as a spike. Uranium was separated from aluminium in the form of chloro complexes by sorption on anion exchange resin Dowex 1-X8 from 9M HCl. The error of determination lies in an interval 0.03–0.07% rel. for uranium contents 18.2–22.8 wt%.
