<p>An improved process for contacting and removing iodine and particularly alkyl iodides from an air stream comprising the use of a relatively concentrated nitric acid solution comprising mercuric ions recycled through a gas contactor. Concurrently, a minor fraction of the solution is passed through an evaporator to oxidize and concentrate the accumulated iodine causing it to precipitate as mercuric iodate, thereby allowing essentially complete recycle of the mercury and nitric acid.</p> |
