Abstract
An adsorbent for oral administration, characterized by comprising a surface-modified spherical activated carbon, having a diameter of 0.01 to 1 mm, a specific surface area determined by Langmuir's adsorption equation of 1000 m/g or more, a total amount of acidic groups of 0.40 to 1.00 meq/g, a total amount of basic groups of 0.40 to 1.10 meq/g, and a diffraction intensity ratio, an R value, determined by equation (1) of 1.4 or more. The adsorbents for oral administration exhibit a useful selective adsorbability; that is, a lesser adsorbability of useful substances, and a greater adsorbability of toxic substances, in a body.
