| Abstract: | The direct dyes' decolouring effect which is influcenced by dosage of coal fly ash,initial concentration of the dye solution,pH value and decolouring time was studied in this paper. And the results showed that coal fly ash had a good effect on decolorization of these organic dyes when Initial concentration of the dye solution was 0.006 g/ml?pH value was 2-10 ,the declouring time was 20-30 minutes. |
