| 摘 要： | 采用改进BCR方法提取国家土壤成分分析标准物质(GBW07401,GBW07402)和水系沉积物成分分析标准物质(GBW07307,GBW07309)中的锑元素化学形态,用ICP-MS进行测定.各个形态含量之和与样品中元素总量测定值基本相符,回收率在108%~125%.同时以湖底沉积物顺序提取微量元素标准物质(GBW07436)作为质控样品验证方法的准确度,检测结果与标准值吻合良好.

| Abstract: | Optimized BCR sequential extraction procedure was applied to Chinese reference materials (GBW07401,GBW07402,GBW07307,GBW07309).Antimony concentration was measured by ICP-MS.The sum of extractable mass fractions of Sb plus residue concentration was compared to total content.Recovery was 108%-125%.Lake sediment for extractable trace elements (GBW07436)was used for quality control and the result was in agreement with certified values. |
