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.
A method of removing undesirable gas phase material from an air stream comprising the steps of interposing a plurality of at least partially hollow wicking fibers in the air stream, with each wicking fiber having a least one slot extending along the wicking fiber and connecting the wicking fiber hollow internal region to an outer surface, and supplying a liquid including a component having an affinity for the undesirable gas phase material to the wicking fibers at a location outside the air stream whereby the wicking fibers can convey the liquid by capillary action into contact with the air stream along the slots while maintaining relatively open interstices between the fibers so that the air stream flow is substantially unimpeded by the liquid.
