Process for removing hydrogen phosphide from waste air

摘要

For removing hydrogen phosphide from waste air, the hydrogen phosphide-containing waste air is passed at temperatures from 50 DEG to 350 DEG C. over a catalyst which is composed, at least on its surface, of at least one metal which, in a 1-molar acidic aqueous solution, has a potential which is at least 200 mV more positive than that of the standard hydrogen electrode.
