%X This paper aims at the reutilization and stabilization of municipal solid waste incineration (MSWI) fly ash to produce a high value added product. The effects of anionic chelating surfactants on the surface modification and fixing capacity of MSWI fly ash were primarily explored. Based on the indexes of active ratio and analysis of IR-spectrometer, the active ratio of ACS1 modified fly ash can be found higher than 95% under the condition of surfactant dosage at 7.0mL/100g fly ash, modification time at 15min and temperature at 75 degrees C . Moreover, Anionic chelating surfactant shows a strong fixing capacity for heavy metals by the United States Environmental Protection Agency's Toxicity Characteristic Leaching Procedure (TCLP).
