摘要
文章建立了氢化物-原子荧光光谱法测定锑矿石中汞的方法。试样用盐酸缓慢溶解,加硝酸进一步消解溶样,对测定条件、干扰进行了相关讨论。在仪器最佳条件下,方法的回收率为96.2%-102.7%,检出限为0.028 ng/mL,相对标准偏差（NSD,n=11）为2.63%-5.89%。该方法简便、快捷,有较高的灵敏度、准确度、精密度。适用于锑矿石中汞（0.0001%-0.010%）的测定。
This article has established a method for the determination of mercury in antimony ores by hydride generation atomic fluorescence spectrometry. The sample was dissolved in hydrochloric acid, and then further dissolved in nitric acid. The effects of determination condions and interference were discussed. Under the optimal working conditions of instrument, the recovery of this method was 96.2% - 102.7%, the detection limit was 0.028 ng/mL,and the relative standard deviation（NSD, n = 11）was 2.63% - 5.89%. This method was simple, rapid, of low detection limits, sensitive and of accurate, and it was suitable to be used in the analysis of Hg（0. 000 1% - 0. 010% ）in antimony ores.
