| Abstract: | Objective：To establish a method for the determination of antimony immersion from glass infusion bottles by graphite furnace atomic absorption spectrometry（GFAAS）.Method：The sample solutions were directly determined by GFAAS with palladium chloride and magnesium nitrate as the matrix modifiers.The experimental conditions,such as ashing temperature and atomization temperature, were optimized.Result：A good linearity of antimony was obtained within the range of l-30μg·L^-1（r=0.999 2）.The detection limit was 0.425μg·L^-1.The recovery was 98.2%（RSD=1.3%,n=9）.Conclusion：The method is simple and fast with high sensitivity. |
