摘　　要：探讨用火焰原子吸收光谱法测定甲基磺酸亚锡中铜含量的分析方法。测试样品经王水溶解,在硫酸介质中用盐酸—氢溴酸排除锡等元素的干扰,测定范围铜为0.00005%~0.0015%。A method for the determination of copper in stannous methanesulfonate by flame atomic absorption spectrometry(FAAS)is described in this paper.The test sample was dissolved in aqua regia and the interference of tin and other elements was eliminated by hydrochloric acid-hydrobromic acid in sulfuric acid medium.the determination range of copper was 0.00005%~0.0015%.
