Kinetics of the oxidation of ammonia and amines with hydroxyl radicals in the aqueous phase
Xiaoying Yang, Ye Tao, J. G. Murphy
Abstract
of 9.25, the rate constant of the protonated form is applicable to the overall rate constant of ammonia at pH <7, indicating that this oxidation pathway is not a significant sink for ammonia in acidic aqueous environments. Because of their partitioning characteristics, oxidation of DMA and DEA by OH in aerosol particles could be competitive with oxidation in the gas phase.
