On the other hand, for ⁇ 1 to ⁇ 5, the gas adsorption power was regenerated when left in the air, and the amount of adsorbed gas that was almost equivalent to the first adsorption amount was indicated by the second adsorption amount.
- Kuro iron powder (average 10 // diameter) was kneaded with a CMC binder and water. After impregnating with urethane foam, it was sintered at 1150 to produce a porous iron body, and the chemical solution treatment shown in Table 2 was performed.
- harmful NOx gases, SOx gases, 0 3 Ki de be removed such as gas, also nitrogen compound-based gas with malodor, sulfur compound-based Gas. Lower fatty acids can be removed.
- the air-cleaning composition of the present invention exhibits strong air-cleaning properties even when used for a long period of time.
- the air-cleaning composition of the present invention is different from that described in Japanese Patent Application No. 11-280776, in that H 2 S gas or the like can be used without disposing a solid base. Has strong air cleaning power.
- the composition having air cleaning power according to the present invention also has food freshness holding power.
