摘要
利用热解析冷原子吸收光谱汞直接测量法对粗甘油中微量汞含量进行检测，结果表明：检出限0.0047μg/kg；相对标准偏差1.7%；加标回收率为99.9%~103.5%，该方法具有良好的精密度与准确度，适用于粗甘油中微量汞的测定。
The mercury content in Crude glycerol was measured by thermal decomposition and cold atomicab-sorption spectrometry method. The experimental result showed that： Detection limit 0. 047 μg/kg;RSD =1. 7%;Recovery 99. 9~103. 5%. The method had good precision and accuracy, suitable for the determination of trace mer-cury in crude glycerin.
