<p>PROBLEM TO BE SOLVED: To provide a highly effective deodorizing substrate against malodorous gas which consists of acetic acid, acetaldehyde, hydrogen sulfide and others. SOLUTION: Composing this deodorizing substrate with phosphate compound which is made of stratified phosphate intercalated with polyamine represented by a chemical formula: H2 NC2 H4 (NHC2 H4 )x-1 NH2 [provided that the x is an integer of 1∼5] or polyamine represented by a chemical formula: H2 NC3 H6 (NHC3 H6 )y-1 NH2 [provided that the y is an integer of 1∼3]. Preferable amount of polyamine intercalated to 1g of stratified phosphate is 0.5∼4 millimol, and zirconium phosphate, titanium phosphate, cerium phosphate and aluminum dihydrogentripolyphosphate are preferred as the stratified phosphate.</p> |
