摘　　要：提出了铁矿石中汞含量的原子荧光光谱测定法。通过试验确定了溶样方法、试液酸度、干扰元素的允许量及仪器工作条件。该方法检出限为0.032μg/L,精密度为4.5%,线性范围为0～40μg/L,加标回收率为97.2%～104.8%,可应用于铁矿石中汞含量的日常检测。The Atomic Fluorescence Spectrometry is pointed out to measure the Hg content in iron ores. Based on this, the dissolution method, samples＇ acid, the allowance of disturbing elements and the optimum working conditions for devices were determined. The results show that this method with the detection limit of 0. 032 μg/L, the accuracy of 4.5% , the linear area of 0 - 40 μg/L, the recovery rate of 97.2% - 104.8% can be adopted as daily inspection of Hg content in iron ores.
