<p>PURPOSE:To remove a malodor substance by supporting divalent transition metal ion on a clay interlayer compd. CONSTITUTION:Porous clay interlayer compd. bridged with metal compd. such as Al2O3, SiO2, among layers, produced by reacting clay mineral with polynuclear hydroxide ion of metal, etc., and by calcining, is forced to coexist with an aq. soln. of metal compd. such as sulfate, nitrate, halogenide of transition metal such as Fe, Ni, Cu, Zn. Thereafter, the transition metal ion such as Fe<2+>, Cu<2+>, Zn<2+>, Ni<2+> is supported on the clay interlayer compd. by drying to obtain the deodorant having large absorption rate.</p> |
