Vaporized Hydrogen Peroxide VHP has been utilized for more than a decade to sterilize clean rooms and pharmaceutical processing equipment and, quite recently, to decontaminate anthrax-ridden buildings. VHP is also suitable for the decontamination of VX and HD, which readily converts these agents to ethyl methylphosphonic acid and bis2-chloroethyl sulfoxide, respectively. However, GD is quite stable in the presence of VHP. The simple addition of low-levels of ammonia gas renders VHP reactive towards GD, converting it pinacolyl methylphosphonic acid. Thus, with suitable activation via ammonia gas, VHP affords the broad-spectrum decontamination of VX, GD, and HD. Potential decontamination applications for this gaseous reactant system include buildings, vehicle and aircraft interiors, and sensitive equipment.
