Abstract

A method is for selectively removing gaseous pollutants from the ambient air, and a device is for implementing the method. Undesirable emissions may be selectively and completely removed from the ambient air using relatively simple equipment and a small amount of energy. Pollutants contained in the air to be purified are ionized by the action of optical radiation, based on resonant and/or non-resonant single-photon excitation and/or multiple-photon excitation, so that the ionized pollutants are drawn off and removed from the air to be purified, using an electric field. A small portion of the energy necessary for the ionization may also be applied in the form of microwave energy or electric-field energy. The method and device may be used in air-conditioning or other air-circulation systems.
