A sorbent treatment process has been developed which uses flyash as sorbent in the treatment of highly toxic and hazardous chemicals; these include: Alcohols, Aldehydes, Ketones and Aromatics. Batch, as well as dynamic, studies were performed, in different phases, during the investigation. Single and multiple solute systems were examined separately. The samples were analyzed using a Flame Ionization Detector Gas Chromatograph.

The result of this study demonstrates that isolation/ immobilization of the organic pollutants is technologically feasible by adsorbing the contaminants onto flyash. The residual carbon content of the flyash plays a very significant role during the treatment process. The sorption of the organic compounds onto flyash is believed to occur principally via the weak induction forces of London or dispersion forces which are the characteristics of the physical adsorption. The treatment efficiency depends on the characteristics of the solute, the sorbent and the solution. The existance of interaction and competition among the solutes, for adsorption sites, is clear in the case of a multiple solute system.
