An analytical method has been developed at the Bureau of Mines Avondale Research Center for determining uranium in phosphate rock processing and waste materials using a combination of preconcentration and x-ray spectrography. Previous work has shown the usefulness of resin-loaded papers for preconcentration in x-ray analysis on samples of varying matrices. This method allows the determination of other radio-nuclides in the sample while avoiding the use of alpha spectrometry for determining uranium. A roundrobin analysis of phosphate material samples involving this center and other Bureau of Mines research centers gave results that agreed with values obtained by accepted procedures. Good agreement was also obtained for the certified value of uranium in National Bureau of Standards SRM 120b phosphate rock.
