The possibility of treating industrial coal combustion ash by sieving, demineralization, steam and CO2 gasification to improve its adsorption capacity has been investigated. A combination of experimental techniques allowed to follow the ash physico-chemical and morphological changes induced by the different beneficiation treatments. Cadmium adsorption equilibrium and kinetic tests were carried out and the results were interpreted in the light of existing models. The effects of the activation treatments have been discussed in order to individuate the most efficient beneficiation methods able to make this extensively-generated industrial waste re-usable in wastewater purification processes.

Abstract
The possibility of treating industrial coal combustion ash by sieving, demineralization, steam and CO2 gasification to improve its adsorption capacity has been investigated. A combination of experimental techniques allowed to follow the ash physico-chemical and morphological changes induced by the different beneficiation treatments. Cadmium adsorption equilibrium and kinetic tests were carried out and the results were interpreted in the light of existing models. The effects of the activation treatments have been discussed in order to individuate the most efficient beneficiation methods able to make this extensively-generated industrial waste re-usable in wastewater purification processes.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
