The Ozonation of Natural Waters: Product Identification

Abstract
Aqueous solutions of fulvic acid have been ozonated under simulated water treatment plant conditions and the oxidation products identified by gas chromatography–mass spectrometry. The predominant oxidation products include numerous alkyl phthalates, mono– and di–carboxylic aliphatic acids and a few cyclic keto–compounds. Ozonation of high–fuivic creek water gave many similar products. The significance of these compounds in finished drinking water is briefly discussed.
