Abstract

Optimum amounts of inorganic salts ( monovalent, divalent, and trivalent chlorides ) added to various bituminous coal fly ashes in batch adsorption treatment experiments indicates the possibility of improving adsorption capacity.

Experiments were conducted on aqueous solutions of three priority pollutants : phenol, toluene, benzene. Both high fusion and low fusion fly ashes were used as sorbent materials. Removal of organic pollutants was measured using a total organic carbon analyzer.

Isotherm tests positively indicate that the addition of inorganic salts to fly ash significantly increases adsorption capacity. The study shows that removal of organic pollutants by fly ash depends on several factors, such as concentration of inorganic salt, pH, washing procedures, and chemical properties of the fly ash and pollutant.

In demonstrating the technical feasibility of utilizing a byproduct material (fly ash ) to treat aqueous solutions contaminated with organic pollutants, this study has indicated an alternative treatment technology that is economically attractive.
