摘要
本文研究了氢化物 -原子荧光光谱法 (HGAFS)测定高纯铅中微量杂质硒。考察了最佳测定条件及共存元素对测定结果的影响。本方法操作简便、快速。结果准确 ,相对标准偏差小于 10 % ,加标回收率为86 .3%— 91.8%。
A method for determination of trace Se in high pure lead has been developed with the help of hydride generation atomic fluorescence spectrometry(HG AFS).The optimum experimental conditions and the effect of coexistent elements on the determination of Se are also investigated.The method shows simple and rapid.The relative standard deviations is less than 10%.The recovery is between 86.3% and 95.1%.
