される。Action The feature of the present invention is that a tetrapot-shaped zinc oxide whisker is basically used. Further, as a basic structure, as shown in FIG. 1, various adsorbents are supported on a tetrapot-shaped zinc oxide whisker. Therefore, in the present invention, since the carrier has a tetrapod-like structure, the ventilation resistance in the deodorant is low, and the chance of association between the malodorous component such as hydrogen sulfide and ammonia gas and the adsorbent is extremely high, so that the deodorant having a fast adsorption rate Will be realized. Moreover, the tetrapod-shaped zinc oxide whiskers that are the carrier directly act as a desulfurizing agent, that is, react with sulfur compounds such as hydrogen sulfide, and thus become an absorbent such as hydrogen sulfide. A volume of deodorant is realized.
実 施 例 以下に本発明の実施例について具体的に説明する。EXAMPLES Examples of the present invention will be specifically described below.
本発明で用いるテトラポット状酸化亜鉛（以下ZnOと
略記する）ウィスカーは、表面に酸化皮膜を有する金属
亜鉛粉末を酸素を含む雰囲気下で加熱処理して生成させ

真であり一例を示す。この写真により、本発明に用いる
ZnOウィスカーの形状的，寸法的特長が明確に認められ
る（テトラポット構造）。The tetrapot-like zinc oxide (hereinafter abbreviated as ZnO) whiskers used in the present invention can be produced by heat-treating a metallic zinc powder having an oxide film on its surface in an atmosphere containing oxygen. The obtained ZnO whiskers have an apparent bulk specific gravity of 0.02 to 0.1, a high yield of 70 wt% or more, and are extremely mass-producible. FIG. 1 is an electron micrograph showing an example. This photograph is used in the present invention
The shape and dimensional features of ZnO whiskers are clearly recognized (tetrapot structure).
この場合、ZnOウィスカー中に、針状結晶部が３軸、

さらに、不純物の含有量も少なく、原子吸光分析の結
果、ZnOが99.98％であった。In this case, the needle-like crystal part has three axes in the ZnO whisker,
Alternatively, two axes, or one axis may be mixed, which is considered to be caused by a part of the four axes broken. The X-ray diffraction patterns of these whiskers all showed ZnO peaks, while the electron diffraction analysis results also showed perfect single crystallinity with few transitions and lattice defects.
Furthermore, the content of impurities was small, and as a result of atomic absorption analysis, ZnO was 99.98%.
また、脱臭作用の面から、針状結晶部の基部から先端
までの長さが６μｍより小さなウィスカーが大きな割合
（例えば80wt％以上）を占める系は通気抵抗が大きくな
り好ましくない。Further, from the viewpoint of deodorizing action, a system in which whiskers having a length from the base to the tip of the needle-shaped crystal portion of less than 6 μm occupy a large proportion (for example, 80 wt% or more) is not preferable because the ventilation resistance becomes large.

形成した（長さ10cm）。Example 1 Tetrapot-shaped ZnO whiskers were produced by the method described above. The length from the base to the tip of the needle-shaped crystal part of this whisker is distributed in 50 to 150 μm, and the thickness of the base is 0.5 to 1.2 μm.
It was distributed in m. Add crushed charcoal (6-10
Mesh (50 wt% crushed coal) was mixed and packed in a cylindrical container made of gas (30 mmφ) and uniformly pressurized at 1 kg / cm 2 to form a deodorizing portion (10 cm in length).

を示している。Air containing H 2 S was introduced into this cylindrical container, and the results of measuring the concentration of H 2 S at the inlet and outlet of the deodorizing section are shown in FIG. In addition, FIG. 2 also shows the results when ZnO whiskers alone were used, and it is shown that even when ZnO whiskers alone are used, the deodorizing effect is slightly inferior to that of Example 1, but it has a considerably high deodorizing ability.
（比較例１） 実施例１と同じ破砕炭を、ポリエステル不織布に均一
に分散し（50wt％）、実施例１と同様に脱臭部を形成し
