PROBLEM TO BE SOLVED: To develop an adsorbent capable of efficiently adsorbing the above-mentioned adsorbed component over a long period of time in adsorbing aldehydes as the adsorbed component, and further utilizing the adsorbent. Provided are an adsorption apparatus, other articles, and an adsorption method capable of easily removing components to be adsorbed on a small scale. SOLUTION: The adsorbent according to the present invention comprises a zeolite-containing adsorbent, wherein the component to be adsorbed is an aldehyde, and the ionic species of the zeolite is N H 4 type, the crystal structure type is ZSM-5 type or ferrierite, and the zeolite has a SiO 2 / Al 2 O 3 molar ratio of 30 to 190, and further reacts with the aldehyde to adsorb the aldehyde Quaternary ammonium salt It is supported on the zeolite. When the component to be adsorbed is formaldehyde, the zeolite is composed of an adsorbent whose ionic species is NH 4 type. |
