改进BCR法分析土壤和沉积物标准物质中锑的化学形态
Extractable mass fractions of Sb in reference materials obtained by optimized BCR sequential extraction procedure
摘要
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.关键词
