盐湖卤水中铀的激光液体荧光法测定

Abstract

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
