Abstract

See full text

A filter device and technique are described which rely on absorption rather than adsorption for the removal of gas phase contaminants. A filter media is composed of wicking fibers which are impregnated with any of a variety of liquid phase absorbing systems made from the combination of a carrier liquid and soluble complexing/degrading agent or agents. The wicking fibers may be connected to an external reservoir which can be used to supply fresh absorbing fluid to the filter media giving them a potentially inexhaustible capacity. The filter media may be made from any of a variety of fibers which can rapidly transport a liquid phase by the nature of either their geometry or their chemical composition. Geometries may include multilobal cross-sectional configurations, porous hollow fibers, porous or striated fibers or tightly bundled microfibers, all of which exhibit the property of wicking fluid from an external source.
