PROBLEM TO BE SOLVED: To provide activated carbon particles capable of achieving higher deodorant effect against an unpleasant odor of an acetaldehyde etc. with a small amount of activated carbon, and a method for manufacturing the same.SOLUTION: (1) The method for manufacturing deodorant activated carbon particles (A) includes: having activated carbon particles (a) whose surface acid group amount is 0.2 mmol/g or more and whose pore volume is 0.7-3.0 cm3/g contain an aqueous solution of 5-35 concentration mass% of a specific hydroxyamine compound in an amount of 85-120% of the maximum water absorption in the activated carbon particles (a) and then drying it. (2) A method for manufacturing deodorant composite activated carbon particles has a step of mixing the deodorant activated carbon particles (A), that contains the hydroxyamine compound obtained by the method (1), and deodorant activated carbon particles (B) that contains a basic substance-removing agent.COPYRIGHT: (C)2012,JPO&INPIT【課題】アセトアルデヒド等の不快臭に対して少量の活性炭で、より高い消臭効果を得ることができる活性炭粒子及びその製造方法を提供する。【解決手段】(1)表面酸性基量が0.2mmol/g以上、細孔容積が0.7~3.0cm3/gである活性炭粒子(a)に、特定のヒドロキシアミン化合物の濃度5~35質量%の水溶液を、該活性炭粒子(a)における最大吸水量の85~120%となる量で含有させた後、乾燥させる消臭用活性炭粒子(A)の製造方法、及び(2)前記(1)の方法で得られたヒドロキシアミン化合物を含有する消臭用活性炭粒子(A)と、塩基性物質除去剤を含有する消臭用活性炭粒子(B)を混合する工程を有する消臭用複合活性炭粒子の製造方法である。【選択図】なし
