PROBLEM TO BE SOLVED: To provide an active carbon having acidic odor and excellent in deodorizing performance by processing to make an alkaline adjuvant adhere to an active carbon having a small pore diameter, which is a low activated carbon, without inhibiting physical adsorption performance while suppressing the elimination of a physically adsorbed odor constituent.SOLUTION: The active carbon is characterized in that 1-20 wt.% of a hydrogen carbonate or a hydroxide adheres to an active carbon having a specific surface area of not greater than 1,000 m2/g.COPYRIGHT: (C)2012,JPO&INPIT【課題】細孔径の小さい活性炭、すなわち賦活度の低い活性炭に、物理吸着能を阻害することなくアルカリ性添着剤を添着加工することで、物理吸着した臭気成分の脱離を抑制しつつ、酸性臭気の脱臭性能に優れた活性炭を提供することを課題とする。【解決手段】比表面積が1000m2/g以下の活性炭に、炭酸水素塩または水酸化物を1~20wt%添着した活性炭。【選択図】なし
