摘要
PROBLEM TO BE SOLVED: To provide a method for modifying activated carbon so that the activated carbon can stably adsorb aldehydes and hydrocarbons without impregnating an aromatic amine compound of a large molecular size into the activated carbon and to provide modified activated carbon and an adsorbent using the modified activated carbon. SOLUTION: In the method for modifying activated carbon, the activated carbon having 10-100 pore diameter and 0.2-1.5 cc/g volume of the micropores is heat-treated in a solvent of = pH 7 at 40-200 deg.C. The modified activated carbon is obtained by modification by the modifying method. And an adsorbent using the modified activated carbon is provided.
