Chlorine is commonly used to disinfect drinking water. However, reactions can take place between the disinfectant chlorine and organic material present in water to produce disinfection byproducts. The halogenated organic byproducts formed usually exist in low concentrations (μg/L), yet some are considered carcinogenic. In this study, the removal of two disinfection byproducts, chloroform and trichloroacetic acid, from water using two hydrophobic molecular sieve zeolites, silicalite-1 and dealuminated zeolite Y, was evaluated. Silicalite-1 was found to adsorb more of the disinfection by-products than the dealuminated zeolite Y at low concentrations. And it was also found that chloroform adsorbed to a greater extent than trichloroacetic acid on both zeolites. The presence of humic acid in the water did not significantly affect the adsorption extent. Subsequent regeneration of the zeolites using advanced oxidation was also found to be successful.
