<P>PROBLEM TO BE SOLVED: To provide adsorbents for oral administration, which exhibit a useful selective adsorbability, that is, a less adsorbability of useful substances in a body, and a greater adsorbability of toxic substances. <P>SOLUTION: An adsorbent for oral administration, characterized by comprising a spherical activated carbon prepared from a thermosetting resin as a carbon source, wherein a diameter is 0.01 to 1 mm, and a specific surface area determined by Langmuir's adsorption equation is 1000 m<SP>2</SP>/g or more; and an adsorbent for oral administration, characterized by comprising a surface-modified spherical activated carbon prepared from a thermosetting resin as a carbon source, wherein a diameter is 0.01 to 1 mm; a specific surface area determined by Langmuir's adsorption equation is 1000 m<SP>2</SP>/g or more; a total amount of acidic groups is 0.40 to 1.00 meq/g; and a total amount of basic groups is 0.40 to 1.10 meq/g. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
