摘要：
Fly ash collected from municipal solid waste (MSW) incinerator have been characterized in terms of chemical constituents, mineralogical components, acid neutralizing capacity and total salt content. It was found that the fly ash is rich in SiO2, Al2O3, CaO, Fe2O3 and MgO, which may act as glass-formers (SiO2 and Al2O3), melting (Fe2O3) and stabilizing agents (Fe2O3) during thermal treatment process. Major mineralogical components of fly ash involve SiO2, CaCl2, Ca3Si2O7, Ca2SiO4 center dot 0.35H(2)O, Ca9Si6O21 center dot H2O, K2Al2Si2O8 center dot 3.8H(2)O and AlCl3 center dot 4Al(OH)(3)center dot 4H(2)O. Aqueous solution of fly ash is alkaline with pH over 11. pH and liquid to solid ratio followed the following equation: y=14.905x(-0.0338), in which y represents pH value and x liquid to solid ratio. Total salt content is 61%.
