Abstract

The chemical state of the trace element Pb, which is contained in municipal solid waste incineration residues discharged from a stoker-type incinerator were investigated by using XAFS spectroscopy at beam line BL 01 B 1 in SPring-8. The chemical states of Pb contained in grate ashes were at an oxide state of Pb²⁺, and it was observed that the amorphous double-oxide compound PbSiO₃ was formed. Boiler ashes were mixtures of the compound oxide of the amorphous PbSiO₃ and either the chloride of Pb²⁺ or the carbonate. As for cooling tower ash, no existence of the chloride was observed only the amorphous PbSiO₃. In APC residues, if the discharged time in the same facility was different, there were both cases : either the chloride, or the amorphous PbSiO₃.
