| Summary: | A new fluorophotometer was constructed and several experiments were carried out from the standpoint of the rapid determination of uranium in human urine. The experiments were carried out on the subjects such as; the effect of the fusion time, the optimum composition and amount of the fusing agent, the quenching of fluorescence by coexisting calcium and magnesium, the relation between fluorescence and the sample amount, the distribution of the intensity of fluorescence in the fused cake, cleaning of the platinum dish, and the detection limit of uranium. The author used a platinum dish (25mm in diameter, 1.0mm in depth), and the fusion was carried out on a open gas-oxygen burner. The evaporated residue of 1ml of sample urine was fused with 0.8g of the fusion mixture (NaF+NaKCO3) in a platinum dish for 2min at 850°900°C. The detection limit of uranium was 0.0010.002μg/ml for human urine. The accuracy of the method was about 4% in the presence of 0.011μg of uranium per dish. |
