<p>PURPOSE:To produce a composition capable of cleaning the contaminated air contg. the malodorous gases such as CH3CHO, NH3, H2S and CH3SH generated from the tabacco smoke or putrefaction. CONSTITUTION:A metallic complex obtained by allowing a metal or alloy to react with a polybasic acid and a porous fine carrier impregnated with aniline and phosphoric acid are deposited on the surface of a porous body consisting of a metal or metallic alloy to obtain the composition. Namely, the porous body is allowed to catalytically react with a polybasic acid and dried, the porous fine carrier impregnated with aniline and the porous body are dipped in or coated with a mixed soln. of phosphoric acid and water, and the porous body is dried to produce the composition.</p> |
