【Abstract】 Objective:To establish a method for synchronizing determination of Tin and antimony in soaked liquid of Plastic Pipes for Water Supply by atomic fluorescence spectrometry.Methods: Through optimizing instruments conditions,comparing the effect of different reducers,and exploring the influence of the disturbing ions,the synchronizing determination of Tin and antimony in soaked liquid of Plastic Pipes for Water Supply is established by hydride generator atomic fluorescence spectrometry.Results: The linear calibration curve for Tin is within the range of 0 μg/L~10 μg/L,of which correlative coefficient is 0.9992,and for antimony is within the range of 0 μg/L~10 μg/L,of which correlative coefficient is 0.9993.The detection limits are 0.8507 μg/L for Tin and 0.0424 μg/L for antimony.The recovery rates of spiking standards for Tin and antimony are 102% and 95% respectively.The RSDs are 3.28% for Tin and 2.70% for antimony.Conclusion: The method is simple,accurate and rapid enough for synchronizing determination of Tin and antimony in soaked liquid of Plastic Pipes for Water Supply.更多还原
