生态地球化学土壤样品元素形态分析方法研究

Research on Speciation Analysis of Chemical Elements in Soil Samples for Ecosystem Geochemistry Study

摘要: 对生态地球化学土壤样品,采用振荡提取法提取样品中离子交换态(包括水溶态)、碳酸盐结合态、腐殖酸结合态、铁锰氧化物结合态、强有机质结合态(包括部分硫化物);采用等离子体发射光谱法测定其中Cd、Co、Cr、Cu、Mn、Mo、Ni、Pb、Zn,原子荧光光谱法测定As、Hg、Sb、Se。方法的质量参数满足生态地球化学土壤样品评价形态分析的需要。

Abstract: A method of speciation analysis for 13 elements in solid samples was presented in this paper. The ion-exchange species (including water-soluble species), carbonate species, humic acid species, Fe-Mn oxide species and strong organic mater species (includin
