| Abstract: | An acid pretreatment method for fly ash was introduced.8mol/L H 2SO 4 was used in the experiments and H 2SO 4 can improve its surface greatly,obviously increasing saturated adsorptire capacity of fly ash.A series of decoloring tests were conducted with pretreated fly ash and the best treating condition was found out,obtaining better decoloring effect. |

| Keywords: | adsorption fly ash dye decoloring saturated adsorptive capacity |
