| 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 (including some sulphides) of the elements were extracted from soil samples by vibration extraction method. The elements including Cd, Co, Cr, Cu, Mn, Mo, Ni, Pb and Zn in the extractions were analyzed by inductively coupled plasma atomic emission spectrometry (ICP-AES) and elements including As, Hg, Sb and Se were analyzed by atomic fluorescence spectrometry (AFS). The quality parameters of the method satisfied the demands of the speciation analysis and evaluation in ecosystem geochemistry study. |
