Abstract

Model solutions of the amino acid phenylalanine were chlorinated to seven Cl/N mole ratios. The by-products were characterized using gas chromatography, high performance liquid chromatography, GC/MS, infrared spectroscopy, and nuclear magnetic resonance spectroscopy. At the lower Cl/N ratios N-chlorophenylalanine and phenylacetaldehyde were identified as the main products while phenylacetonitrile and N-chlorophenylacetaldimine were the major products at Cl/N ratios of 2.0 and beyond. The concentration of phenylalanine in a municipal wastewater was determined. Using a radiotracer the chlorination products of phenylalanine in the wastewater at the 7 Cl/N ratios were identified as those seen in the model solutions. The distribution of the byproducts in the wastewater supports the idea that organic monochloramines may represent a significant percentage of the chlorine-containing oxidants present in wastewater at low chlorination levels used in treatment plants.
