PURPOSE:To enlarge the specific surface area and the pore volume and to enhance adsorptivity by blending 0.1-10 pts.wt. water resistant carboxymethyl cellulose with 100 pts.wt. granular activated carbon and pressurizing this compo sition and forming an adsorbent of the molded body. CONSTITUTION:A molded adsorbent is obtained by blending 0.1-10 pts.wt. carboxymethyl cellulose with 100 pts.wt. granular activated carbon and adding water to this composition and kneading the mixture and thereafter pressurizing and molding it and then performing water resistant treatment for this pressu rized and molded body. The granular activated carbon is utilized wherein it is optically anisotropic and at least 90% of the whole body consists of the granules having <=80mum granule diameter and at least 85% of the whole pore volume is constituted of micropores having <=20Angstrom pore diameter. Further the specific surface area of activated carbon is regulated to about 500-4600m<2>/g and the whole pore volume is preferably regulated to about 0.5-3.0ml/g. |
