<P>PROBLEM TO BE SOLVED: To provide an inexpensive anion adsorptive carbon material with an excellent anion adsorption property being environment-friendly, and its production method. <P>SOLUTION: The anion, an object to be adsorbed and the ion-exchangeable anion are bonded to, directly or through the calcium ion, a functional group drawn out from a fine pore wall by bringing an acid solution 3a into contact with the fine pore wall of the carbonized product obtained by carbonizing a material 2 comprising a plant with which a solution H containing calcium ion is contacted. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
