Which scavenging method will not remove nitrous oxide?

Explanation:
Nitrous oxide isn’t effectively captured by chemical absorbents used in scavenging systems. Absorption relies on the absorbent material to chemically react with or dissolve volatile components, but nitrous oxide is relatively inert and passes through these absorbers without being removed. Other methods—desiccation (removing moisture), filtration (trapping particulates and some vapors), and Venturi mixing (diluting waste gas with room air)—don’t rely on chemical capture of the gas, so they won’t remove nitrous oxide either, but they work by different mechanisms. Therefore, the absorption approach will not remove nitrous oxide from the waste gas.
