ている。In the present invention, when the above-mentioned amino group-containing organosilicon compound is used as an acid gas-adaptable component and activated carbon is used as a carrier, the silicon is formed by hydrogen bonding to a functional group (hydroxyl group) on the activated carbon surface. Since the compound is immobilized, the dissolved concentration of the silicon compound in water is stable. On the other hand, activated carbon carrying essential oil has a low dissolved concentration of essential oil, which is a carrier, and has a stable dissolved concentration in water.

ある。According to the present invention, one of the acidic gas-adaptive component and the basic gas-adaptive component is supported on a carrier in water, and the other component remaining in water without being supported on the carrier. The component is removed by a neutralization reaction via the other component eluted from the carrier on which the other component is pre-supported.

臭剤を得ることができる。Since one component does not elute into water and does not neutralize with the elution of the other component, it neutralizes the surplus of one component with the elution of the other component. If the surplus one of the components disappears, the neutralization reaction stops. For this reason, since each component carried on each other's carrier surface is extremely unlikely to be unnecessarily offset by the neutralization reaction, it is possible to obtain both acidic and basic gas deodorizers carrying both components. it can.
