PROBLEM TO BE SOLVED: To provide an absorbent which has a high acidic gas absorption performance and prevents resin deterioration and a deodorant processed product such as paper, non-woven fabric and fiber exhibiting excellent deodorant performance using the absorbent.SOLUTION: An absorbent for acidic gas is represented by a composition formula (1): Na2O mSiO2 nH2O (0.8≤m≤4.40.01≤n≤8.0) and is formed of sodium silicate. An adsorption amount of the acidic gas is 20 mL/g or more, and the average particle size thereof is 0.1-20 μm. Paper, non-woven fabric, fiber and a plastic molded article show little defects in the appearance such as coloration and discoloration and exhibits a high deodorant performance, and the adsorbent is applied or kneaded thereto.SELECTED DRAWING: NoneCOPYRIGHT: (C)2018,JPO&INPIT【課題】酸性ガス吸着性能が高く、樹脂劣化を生じない吸着剤、又、当該吸着剤を用いて優れた消臭性能を発揮する紙、不織布及び繊維などの消臭性加工製品の提供。【解決手段】下記組成式(1)で表される珪酸ナトリウムからなる酸性ガス用吸着剤。酸性ガスの吸着量が20mL/g以上であり、その平均粒度が0.1~20μmである、酸性ガス用吸着剤。又、着色や変色などの外観上の不具合が少なく、高い消臭性能を発現する前記吸着剤を塗布又は練り込み加工した紙、不織布、繊維、プラスチック成形品。Na2O・mSiO2・nH2O・・・(1)(0.8≦m≦4.4;0.01≦n≦8.0)【選択図】なし
