文摘

Uranium has been determined in seawater, biological samples and sediments using laser induced fluorescence spectrometry (LIFS). The biological samples and sediments are digested with a mixture of HNO<sub>3sub>, HClO<sub>4sub> and HF. The conductivity of the seawater should be below 5.0 mS and the pH of the sample should be in the range 6.5–9.0. The volume of the reagent used to enhance the fluorescence intensity was 0.5 ml. Comparison with other methods was favorable, LIFS being rapid, simple and sensitive, and well suited to environmental monitoring.
