Modification of coal fly ash for high capacity adsorption of methylene blue

Modification of coal fly ash for high capacity adsorption of methylene blue

Coal fly ash (FA) waste from local thermal power plant has been modified by acid activation and SiO2 enrichment using hydrochloric and acetic acids. The modified FA with acid activation (FAA_HAc and FAA_HCl) and SiO2 enrichment (SiO2_HCl and SiO2_HAc) were applied in the adsorption of methylene blue...
