Abstract
A method of purifying air polluted by smoke and fumes, such as from wildfires and other hazard, may deploy a series of fluid filled vessels that act as filters to trap and/or neutralize components that would foul an aqueous suspension of gold nanoparticles that is effective in converting toxic carbon monoxide to carbon dioxide. Non-toxic fluids may be used. As the gold nanoparticles are effective in a basic solution, the solution may contain a visible pH indicator or an apparatus that deploys the method may continuously monitor the pH thereof.
Claims9
A process for remediating contaminated air, comprising the steps of:
- a. forcing contaminated air into an oil filter,
- b. directing the air that exits the oil filter into an alkaline fluid,
- c. directing air that exits the alkaline solution into a catalytically active fluid that contains colloidal gold nano particles (AuNPs) dispersed in an alkaline aqueous solution, wherein at least partially purified air exits the catalytically active fluid.
