Reducing Heavy Metal Element from Coal Bottom Ash by Using Citric Acid Leaching Treatment

Coal ash is the residue that is produced during coal combustion for instance fly ash, bottom ash or boiler slag which was primarily produced from the combustion of coal. With growth in coal burning power station, huge amount of coal bottom ash (CBA) considered as hazardous material which are normall...

With growth in coal burning power station, huge amount of coal bottom ash (CBA) considered as hazardous material which are normally disposed in an on-site disposal system without any commercialization purpose.

In this study, the weaker acid, citric acid solution was used to replace the strong acid in leaching treatment process.
