Abstract : Chlorine is used nearly universally for disinfection water and wastewater in the United States, and in other parts of the world. The present work has been concerned with an examination of kinetic aspects of Cl (+) transfer from Chloroamine to other nitrogenous compounds and the impact of these reactions on the overall fate of active chlorine in the aqueous environment. The investigation of Cl (+) transfer from NH2Cl to organic nitrogenous compounds involved various catagories of receptors: (1) amines (methylamine, dimethylamine and morpholine) (2) amino acids (glycine, serine, alanine, tryptophan and sarcosine), (3) glycine derivatives (glycylglycine and glycine ethyl ester), and (4) amides (N-acetyl glycine). It is concluded that the transfer is a second-order process - - first-order in each reactant. Results indicate that the transfer of Cl (+) to NH2Cl readily occurs with specific rates which vary at 25 C and pH approx. 7 from approx. 14 (mol/L) s for morpholine-NH2Cl to approx. 0.140 (mol/L) s for dimethylkamine-NH2Cl reactions.
