激光荧光法直接测定环境样品中的微量铀

用激光荧光法直接测定了环境水样,土壤,生物样品及某些污染物中的铀,并对测定结果进行了分析。结果表明：该方法测定环境样品灵敏度高,线性关系好,对水,土壤和生物样品测定精密度分别为５％,１０％,２０％,从实验室内和实验室间获得的大量榈的数据具有可比性,可以作为常规方法广泛使用。

Direct determination of uranium in environmental samples by laser fluorescence method

A method of uranium direct determination by laser induced fluroscence ispresented- The kinds of samples determined include surface water, soil, biologicalmaterial and some contaminated soils. Results show that the method is sensitive andaccurate, with degree of variation 5%, 10% and 20% for water, soil and biologicalsamples respectively. Results of inter-lab comparisions indicate that results from thismethod are of comparablity. Its high sensitivity and reliability, as well as itsconvemence and low cost will make this method a more attractive option forapplication to envirorunental monitoring.
