| 英文摘要 | In this study, fly ash samples were collected from bag houses in a chinese municipal solid waste incinerator (mswi) and secondary fly ash (sfa) samples were collected from a high-temperature tubular electric furnace by thermal treatment of mswi fly ash at 1050, 1100, 1150, 1200, and 1250 degrees c.we determined the speciation and atomic coordinates of lead in sfa using x-ray absorption spectroscopy (xas) techniques. the results obtained by x-ray absorption near edge structure (xanes) spectra revealed that the mass fraction of pbo in mswi fly ash was 57.9% (wt %) while pbcl2 and pbs were the dominant species in sfa. extended x-ray absorption fine structure (exafs) data analysis indicated the atomic coordinates of pb were proportional to the weights of pbcl2 and pbs, in good agreement with the xanes spectra. these findings highlight lead evaporation processes in the mswi fly ash during heat treatment and provide a method for consistent speciation analysis of environmental samples using xas.
