| Abstract: | 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%. |
