摘要: 采用发射光谱法测定区域化探样品中Pb、Sn、Mo、V元素，以焦硫酸钾、氟化钠、三氧化二铝和碳粉的混合物为固体缓冲剂，采用外加内标法以锗（Ge）作为内标元素，选择合适的分析线对，选取国家一级地球化学标准物质（GBW水系沉积物、土壤）平行测定（n=12次）.测试结果准确度达到规范要求，满足区域化探样品的检测要求.

Abstract: To determine the Pb, Sn, Mo and V contents in the regional geochemical samples by emission spectrometry, select a mixture of potassium pyrophosphate, sodium fluoride, aluminum oxide and carbon powder as solid buffer, Ge as the internal standard element, and also appropriate analysis line pairs and national first-level geochemical standard materials (GBW stream sediments and soil) for parallel determination(n=12). The test results show that the accuracy meets the specification and test requirements of regional geochemical samples.
