摘要
试验了土壤和底泥中砷的前处理技术,其目的是能对土壤、底泥中砷、铬、锰在一次前处理中制备成试液,比色法分析。试验表明,用H2SO4-H3PO4-H2O2进行前处理是可行的。方法简单,挥发酸雾少,用标准参考物质检验证明,分解完全,数据准确,有较好的一致性。
Sample treatment of soil and mud for the analysis of As was tested, with the aim of once digestion for three elements As, Cr and Mn. The test showed treatment with H 2SO 4 H 3PO 4 H 2O 2 is practical. The method is simple with less acidic fog and good precision with standard sample.
