| 摘要: |
| 采用王水浸取样品,用氢化物发生-原子荧光法同时测定重晶石中的砷和汞,并对样品的浸取方法,干扰元素及各种实验条件进行研究。建立的HG-AFS同时测定重晶中砷和汞含量的分析方法,满足进出口检验快速准确的要求。砷和汞的回收率在92.53%~120.00%之间,方法相对标准偏差(RSD)为砷0.77(n=11),汞1.02(n=11),检出限为砷0.45ng/ml,汞0.01ng/ml。 |

| Abstract: |
| A method for the determination of arsenic and mercury in barite by hydride generation atomic fluorescence spectrometry is investigated.The sample is prepared by aqua regia.The effect of concomitant ions and testing conditions are studied.This method can satisfy rapid and accurate requirements.The recoveries of arsenic and mercury are 92.53%~120.00%.The relative standard deviations(n=11) are 0.77 & 1.02 for As & Hg.The detection limits of 0.45ng/ml and 0.01ng/ml have been obtained. |
