Removal of NO and NO2 from Contaminated Atmospheres

Abstract

Laboratory studies were carried out to determine the feasibility of removing certain toxic gases from a vehicle atmosphere. Both nitrogen dioxide (NO2) and nitric oxide (NO) were studied in the concentration range 200 to 2000 parts per million (ppm). Only non-toxic agents were considered for removal of these gases. The most efficient scrubbing agents found were: water, diammonium phosphate and Monnex with NO2, MAP (monoammonium phosphate) and alum with NO. Unfortunately, no single powder showed promise of removing both the toxic gases used in these experiments. The presence of a base (sodium bicarbonate) in the water mist did not enhance the removal of NO2 from the atmosphere. Keywords: Nitrogen dioxide, Nitric oxide, Water spray, Powders, Toxic gases.
