<p><P>PROBLEM TO BE SOLVED: To provide a contaminant removing material by which a very small amount of a gaseous chemical contaminant existing in a gas, in particular a basic gas such as ammonia in the dry gas, can be removed effectively. <P>SOLUTION: One embodiment of this method for manufacturing the contaminant removing material comprises: a step to introduce a polymer side chain having a cation exchange group, a chelate group or a hydrophilic group onto a main chain of an organic macromolecular base material and obtain an organic macromolecular material; a step to deposit the metal ions of a metal salt on the cation exchange group, the chelate group or the hydrophilic group by bringing the metal salt into contact with the obtained organic macromolecular material; a step to oxidize the deposited metal ions and precipitate the obtained metal oxide in the form of fine particles ; and a step to treat the precipitated fine particles with an acid. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
