Reaction of free chlorine with humic substances before and after adsorption on activated carbon.

Abstract

w The reaction of humic acid with aqueous free chlorine was examined before and after adsorption on an activated carbon bed. Capillary and packed column gas chromatography and mass spectroscopy were used to examine whether unique organic compounds were formed by the reaction of chlorine with adsorbed humic materials. The concentrations of chlorine and carbon were typical of those experienced in municipal water treatment plants. The results showed essentially no evidence that compounds formed by reaction of chlorine with adsorbed humic substances were different than those formed from the chlorine reaction with humic materials in aqueous solution and that the use of granular activated carbon would result in lower concentrations of chlorinated products of humic substances than if activated carbon had not been used.
