AN EFFECTIVE METHOD OF SCAVENGING NITRIC-OXIDE

We report an effective method of scavenging nitric oxide and nitrogen dioxide. We have compared three agents, a commercially available filte r, soda lime and activated charcoal, for their effectiveness and durat ion of action. Complete absorption of nitric oxide and nitrogen dioxid e for a period of 170 h was obtained using the commercial filter. Howe ver, soda lime and charcoal were unable to successfully scavenge eithe r gas. The resistance characteristics of this filter when dry or humid ified were determined.
