摘要
采用王水（1＋1）水浴分解样品,氢化物发生-原子荧光光谱法（HG-AFS）测定金矿石中高含量的锑.其方法回收率在95.0%-102.0%之间,相对标准偏差在1.0%-3.4%之间,方法检出限为3.0×10-10g/mL,经试验证实该方法可测范围宽、简便、快速、准确,实验室间对比分析结果吻合程度令人满意.
With aqua regia-water bath to decompose the sample,a method for the determination of high content Sb in gold ore by hydride generation-atomic fluorescence spectrometry（HG-AFS）is reported.The method recovery is 95.0%～102.0%,the relative standard deviation is 1.0%～3.4%,detection limit is 3.0×10-10 g/mL.Experiments rerified that the method has the adventages of wide measurement range,simplicity.rapidity and higher accuracy.The results of contrast analysis among laboratories are satifactory.
