Solvent, extraction-ICP atomic emission spectroinctry was applied to the determination of uranium in apatite minerals. Apatite minerals were treated with nitric acid. After removing a small quantity of insoluble residue, uranium was extracted with 0.05 mol/dm^3 1-phonyl-3-mcthyl-4-trifluoroacetyl-5-pyrazolonc-diisobutyl kctone at pH 0.8. The uranium content in the apatite was found to be (20.3〜132.9)×10^<-4>%.
