| Abstract: | Purpose： A analytical method is recommended for determination of Trace Amount of Antimony in Lead-Tin Alloy by hydride generation double channel atomic fluorescence spectrometry,which provides basis for its measurement.Methods： Optimum condition for the instrument determination is applied to conduct researches relating to the method of sampling,concentration of KBH4,detection limits and recovery rate.Results： The standard curve of the linear equation was y=157.56x-2.3962 with correlation coefficient γ = 0.9999 and linear range of 0～40 μg/L.The precision and the detection limits were 1.3 % and 0.0304 μg/L respectively while the returns-ratio achieves 115 %.Conclusion： The method is easy,fast,highly sensitive and with no much interference during the operation,which can lead to satisfactory results. |
