Kinetics of nitric oxide oxidation

Nitrogen oxides are nowadays a subject of global concern. Several types of nitrogen oxides exist in the environment: N(2)O, NO, NO(2), N(2)O(3), N(2)O(4), N(2)O(5). The abbreviation NO (x) usually relates to nitric oxide NO, nitrogen dioxide NO(2), and nitrous oxide N(2)O. The first two are harmful pollutants for both environment and human health, whereas the third is one of the greenhouse gases. Implementation of stringent NO (x) emission regulations requires the development of new NO (x) removal technologies from exhaust gases. One of many proposals for NO (x) emission reduction is the application of an oxidizing agent which would transform NO (x) to higher nitrogen oxides with higher solubility in water. The main objective of the paper was to present the rate constant of nitric oxide oxidation, determined in our studies.
