Kinetics of Monochloramine Reactions with Nitrite
Publication: Journal of Environmental Engineering
Volume 120, Issue 4
Abstract
Kinetics of reactions in solutions containing monochloramine and nitrite were evaluated as a function of pH, temperature, excess ammonium, and initial concentrations of monochloramine and nitrite. The disappearance rates followed a first‐order reaction with respect to . The observed reaction rates for nitrite were proportional to . The rate of the reaction was inversely proportional to . The activation energy at pH 7 was relatively low, 13.4 kJ. Phosphate catalyzed the reaction. The analysis of both reactant and by‐product concentrations indicated that nitrogen in was not fully oxidized to , nitrogen in was not completely converted to , and the stoichiometric molar ratio of the disappearance of was not exactly 1.
