| 内容記述 | [Abstract] Solvent extraction with inductivery coupled plasma atomic emission spectrometry (ICP-AES) was applied to the determination of uranium in apatite minerals. The combination of 3-phenyl-4-benzoyl-5-isoxazolone (HPBI), a highly acidic extracting reagent (pKa=1.23), and diisobutyl ketone (DIBK) make it possible to exit uranium from a very low pH region where uranium is separated from the interfering elements and the precipitation of calcium phosphate is avoided. Apatite minerals were treated with concentrated nitric acid. After removing a small quantity of insoluble residue, uranium was extracted with 0.06 mol/dm3HPBI into DIBK at pH0.3 in order to separate it from the interfering elements. Uranium was determined by ICP-AES and direct injection of the DIBK phase. A wavelength of 367.01nm was selected which gave the highest intensity ratio,i.e., the emission intensity of uranium in DIBK to the background one, and the best detection limit (0.02 mg/ml). The uranium content in the apatite was found to be (1.06±0.12)×10-2%. | |||||||||
