摘　　要：采用氢化物发生原子荧光光谱法测定了烧结物中的总砷含量 .烧结物样品通过高压焖罐消解后测定 .AsⅤ的线性范围为 0～ 3 0 0 μg/L .用标准参考物质煤飞灰对方法进行了验证 ,所得结果与标准参考值相符 .本法测定烧结物中总砷含量 ,样品相对标准偏差小于 4% 。A simple and sensitive method was proposed for the determination of total arsenic in sinters by hydride generation atomic fluorescence spectrometry (HGAFS). The method was based on the oxidation of arsenic compounds with strong acid mixtures in the pressure steel bomb. The linear range for As Ⅴ determination was 0～300 μg/L. The method was validated by analysis of standard reference material (coal fly ash) with satisfactory results and was successfully applied to the determination of total arsenic in sinters with RSD less than 4%.
