<P>PROBLEM TO BE SOLVED: To provide a chemical filter capable of enhancing the removal capacity of an ionic gaseous pollutant by fixing a large amount of an ion exchange resin powder to a base material while making it less liable to cause the falling-off of the ion exchange resin powder and reduced in pressure loss, and its manufacturing method. <P>SOLUTION: The chemical filter is obtained by fixing the ion exchange resin powder to the surface and inside of fibrous paper for constituting a corrugated honeycomb base material by an adhesive. In this chemical filter, the mean particle size of the ion exchange resin powder is preferably 1-150 μm and the ion exchange capacity thereof is preferably 1-10 meq/g. The chemical filter is manufactured by applying a mixed slurry comprising the ion exchange resin powder and the adhesive to the corrugated honeycomb base material by spray treatment, shower coating treatment or immersion treatment. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
