METHOD OF DYE REMOVAL FROM WASTEWATER |
| 摘要 |
A method of dye removal from wastewater includes producing activated carbon from heavy oil fly ash and using the activated carbon to adsorb dye in the wastewater. The heavy oil fly ash based activated carbon is produced using phosphoric acid based chemical activation. The dye can be removed from wastewater by contacting the wastewater with the activated carbon. The activated carbon can then be separated from the wastewater to remove the dye, and thereby, purify the wastewater. |

1. A method of dye removal from wastewater, comprising:
impregnating heavy oil fly ash with phosphoric acid to provide an impregnated material; heating the impregnated material to temperatures of about 450° C. to about 900° C. to provide powdered activated carbon (PAC); contacting the wastewater with the powdered activated carbon; adsorbing dye from the wastewater by the powdered activated carbon; separating the powdered activated carbon from the wastewater to remove the adsorbed dye. |
