摘要
采用硝酸-氢氟酸作为消解液,微波消解-电感耦合等离子体质谱法测定土壤中的铊,方法简便、快速.铊的检出限为0.006mg/kg,相对标准偏差(n=7)为2.75~4.55%,该方法用国家一级标准物质验证,结果与标准值相符.
The sample was microwave digested with HNO3-HF,and Thallium in soil were determined by Microwave digestion,the method is simple and rapid.The detection limit of the method was0.006mg/kg,The relative standard deviation(n=7)was 2.75~4.55%,The analytical results of national primary standard was consonant with standard value.
