| 摘 要： | 将金精矿粉样品直接置于石英舟中，在高纯氧气氛中燃烧，释放出汞，与齐化管中的金形成金汞齐，于900℃热释放出汞蒸汽，用直接测汞仪法测定汞的含量。测定结果的相对标准偏差为0．28％～1．57％（n=6），方法检出限为1．0pg／kg，加标回收率为95．7％～117．4％。用该法对4种土壤标准样品进行了测定，测定结果与标准值相符。该方法适合于金精矿粉中微量汞的测定。

| Abstract: | The sample of gold concentrate powder was burned in the quartz boat with high pure oxygen and mercury released after Hg–Au being generated through the collecting tube.Mercury vapor released when the alloy was heated to 90℃,then the mercury vapor was determined by atomic absorption spectrometry.The relative standard deviation of determination results was 0.28%–1.57%(n=6),and the detection limit was 1.0 μg/kg.The recovery was 95.7%–117.4%.Four soil standard samples were measured by this method,and the determination results were confirmed with the standard values.The method is suitable for the determination of trace Hg in gold concentrate powder. |
