摘　　要：建立了灰化处理-火焰原子吸收光谱测定载金炭中银量的方法；经过大量的条件实验，确定了坩埚材料、灰化温度、溶样试剂用量、测定介质酸度等最佳实验条件；在加入一定量单元素及混合元素的条件下，进行了银量测定的干扰实验。该方法操作简单快速、易于掌握，加入标准物质回收率为99．23％～102．5％，适合于批量载金炭样品的测定。An ashing-FAAS（ flame atomic absorption spectrometry） determination method is used in determining silver content ingold-beating carbon. Related parameters such as crucible materials, ashing temperature, dosage of dis- solving agents and acidity of media are determined through lots of experiments. With addition of certain amount of sin- gle element and mixed elements, interference experiment of silver determination is conducted. The method is easy to operate and to master,and recovery rate reaches 99.23 % to 102.5 % with the addition of standard susbstance ,fitful for batch tests of gold-bearing carbon.
