摘要
建立了电感耦合等离子体原子发射光谱(ICP-AES)法测定铅泥中Sn元素定量分析方法。采用Na2O_2熔解样品,通过实验确定了最佳工作条件。实验结果表明方法的检出限为0.2μg/mL,加标回收率在95.0%~104%,相对标准偏差在1.6%~2.8%。方法准确、快速,适用于日常分析对铅泥中锡元素的测定。
An analytical method for the determination of Sn in lead sludge by inductively-coupled plasma atomic emission spectrometry(ICP-AES)was established.Na2 O2 was used to melt the sample and the optimum working conditions were determined by experiments.The experimental results showed that the detection limit of the method was 0.2μg/mL,the recovery of spiked standard was 95.0%—104%,and the relative standard deviation was 1.6%—2.8%.The method is accurate,rapid and suitable for the routine analysis of the determination of tin in lead sludge.
