摘　　要：测定板栗药材中的砷、汞微量元素。一次性微波消解法,利用原子荧光光谱法测定板栗中的砷和汞。3个产地板栗砷、汞的相对标准偏差小于1%,加标回收率在95.0%—99.0%的范围内。本法简单、准确,适用于中药材中砷和汞含量检测。The contents of As and Hg in Castanea mollissima Blume from 3 different regions were determined by HG-AFS with microwave digestion.RSD for As and Hg were less then 1%,sample recoveries were within the range of 95.0%—99.0%.The method is simple and accurate,and can be used for determining the contents of As and Hg in Chinese herbs.
