Abstract

An X-ray spectrometric method for the determination of thorium in a variety of purified uranium materials is presented. The thorium is separated from the uranium prior to X-ray determination by a 2-thenoyltrifluoroacetone-xylene extraction. An acid solution of the reextracted thorium is irradiated in a 100-kv X-ray spectrograph after the addition of strontium as an internal standard. A statistical study indicates a limit of error of ± 7.7 ppm over the concentration range from 100 to 1000 ppm of thorium.
