| 摘 要： | 建立了电感耦合等离子体发射光谱法测定水中铀的方法。优化了仪器工作条件,通过基体匹配消除了无机酸基体干扰。方法检出限为0.15 mg/L,对5.000 0 mg/L铀标准溶液测定的相对标准偏差(RSD)为0.98%(n=10),加标回收率为95%~106%,方法准确可靠。

| Abstract: | A method for the determination of uranium in water by inductively coupled plasma atomic emission spectrometry(ICP-AES) was developed.Instrumental operating parameters were optimized,and the matrix effect of inorganic acid was eliminated through matrix matching.The detection limit was 0.15 mg/L and the RSD was 0.98% for 5.000 0 mg/L uranium solution(n=10).The recovery range was 95%-106%.The accuracy of the method was verified by analyzing the Standard(GBW(E)080173) under optimized operating conditions.The result obtained agreed quite well with that of the Standard. |
