Chlorination of lysine: Products and implications for disinfection of wastewater
- Old Dominion Univ., Norfolk, VA (United States)
Amino Acids such as lysine are one of the organic nitrogen components of municipal wastewater that can react readily with aqueous chlorine at the levels used at treatment facilities. The reactions of lysine model solutions were examined at 5 different Cl/Lys molar ratios. The products were identified by HPLC, NMR, IR, and GC/MS. At low Cl/Lys ratios the major products were N,N`-dichlorolysine and {epsilon}-N-chloraminovaleraldehyde. At higher Cl/Lys ratios the major products included {epsilon}-N,N-dichloramino-valeronitrile and {epsilon}-N,N-dichloramino-N-chlorovaleraldimine. The distribution and yields of these products were determined in a lysine-containing wastewater using a radiotracer. A scheme of pathways is proposed for the formation of the various products at different chlorination levels.
