Fly ashes collected from waste heat boilers in the incineration process may possess representative chemical structure of toxic metals during incineration and their changes in the quench process at 1125-553 K and 503-493 K, respectively. Note that copper may play an important role in catalytic formation of dioxins during incineration. Speciation of copper in the fly ashes has, therefore, been studied by X-ray absorption spectroscopy in the present work. About 24% of nano copper in the fly ash was observed by least-squares-fitted XANES (X-ray absorption near edge structural) spectroscopy. Sintering of the fly ash at 1423 K for 30 min led to a reduction of the nano CuO content to 8%.
