摘要
利用氢化物原子荧光光谱法对人发中的硒进行测定,并选用标准参考物质GHS-1(人发标样)及多个人发样品的加标回收率对方法的准确度和精密度进行验证,所测值与标准值相符,样品的平均加标回收率为96.31%。表明此方法测定的结果可靠。
This article uses hydride occurrence atomic fluorescence spectrometry for the determination of selenium in human hair, choosing standard specimen （the criterion of human hair） and several sample addition recovery rate of human hair to validate the accuracy and precision of this method. The resuits accord with the standard data. The average sample addition recovery rate reaches 96.31 percent, showing the credibility of this method.
