The formation and composition of highly fluorescent zinc phosphates in the presence of traces of uranium were investigated, and a direct fluorimetric determination of uranium in aqueous media was developed, based on the formation of finely dispersed and stabilized fluorescent precipitates. The standard deviation for 20 mu g of uranium in 25 ml is 5%; with the fluorimeter described, 10/sup -2/ mu g of uranium per ml can be determined with an error of 50%. The method is very selective and can be employed for analysis of uranium in ores; it is less sensitive than conventional fluorimetry of fused alkali fluorides but is much simpler and faster. Interferences can often be eliminated by suitable masking reactions. (auth)
