Method and apparatus for air purification
First Claim
1. A method of removing mercury vapor from the atmosphere comprisingmoving the air containing the mercury vapor through a filter of sulfur coated fibers to remove at least part of the mercury vapor from the air;
- moving the air passed through the filter of sulfur coated fibers through an electronic precipitator having an anode through which the air is passed and a cathode on which mercury anions will amalgamate to further remove part of any remaining mercury vapor from the air; and
moving the air passed through the electronic precipitator through an iodine impregnated, activated charcoal filter such that any sulfur and sulfur compounds in the air resulting from passage of the air through the filter of sulfur coated fibers and remaining mercury vapor carried by the air are at least partially removed by intimate contact with the iodine impregnated charcoal of the filter.

Abstract
Apparatus for the collection and removal of mercury vapor from the air. Atmospheric air containing mercury vapor is forced by a blower through a sulfur filter, through an electrostatic precipitator, and into an iodine impregnated, activated charcoal filter. The air moving through the sulfur filter picks up sublimized sulfur and, as the resulting vapor phase sulfur passes through the electrostatic precipitator, some of it reacts with ozone formed therein to form sulfur compounds which are absorbed, along with elemental sulfur, on the iodine impregnated, activated charcoal filter. Some of the mercury vapor not removed from the air as the air is moved through the sulfur filter is removed in the electrostatic precipitator and most of the remaining mercury vapor is removed by subsequent passage through the iodine and sulfur impregnated, activated charcoal filter.
