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 in gold-bearing 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.
