摘要: 针对WGJ-III型微量铀分析仪测铀原理分析,结合卤水的特点以及在大量实验研究的基础上,提出了激光液体荧光-标准加入法测定盐湖卤水中铀的方法。方法检出限为0.02 mg/L,对配制含铀1.000 mg/L卤水测定的相对标准偏差(RSD)为0.98%(n=10),加标回收率为95%~106%。该方法操作简便、分析结果准确且分析成本不高,可用于盐湖卤水或高矿化度水溶液中铀含量的测定。

Abstract: This study is about to establish a method for determination of uranium in salt lake brine.By analyzing determination principle of WGJ-Ⅲ uranium tester and considering characteristics of brine,laser and liquid fluorescence?鄄standardized addition method was put forward based on a lot of experimentations.The detection limit was 0.02 mg/L,the RSD was 0.98%(n=10) for 1.000 mg/L uranium in brine and standard sample recovery rate was at 95%~106%.This method is easy,accurate,and inexpensive,so it can be used to determine uranium in brine or in high mineralization solution.

Key words: uranium, salt lake brine, laser and liquid fluorescence
