Abstract:	`Small amounts (0.0 M-0.01 M) of inorganic salts (sodium chloride, calcium chloride, and aluminum chloride) added to bituminous coal fly ash and granular activated carbon in batch adsorption treatment experiments indicates the possibility of enhancing the extent and rate of adsorption process. Experiments were conducted on aqueous solutions of highly toxic and hazardous chemicals, those include : phenol, benzene, toluene, isopropyl alcohol, and methyl-isobutyl ketone. Single and multiple solute systems were examined separately. Removal of organic pollutants was measured using a Flame Ionization Detector Gas Chromatograph. This study investigated the role of inorganic salts during the sorption process. The results of this study show the improvement of treatment efficiency by the addition of inorganic salts depends on the characteristics of the solute, the sorbent, the salt, and the solution. The results also reveal that the adsorptive capacity of sorbents can establish a linear relationship with the concentration of inorganic salts.
