    摘要: Disclosed herein is a novel porous and spherical carbonaceous product having acidic groups, basic groups, phenolic hydroxyl groups and carboxyl groups as functional groups at the following relationships:(1) the equivalent ratio of the acidic groups to the basic groups is in the range of 0.40 to 2.5 and(2) the value obtained by subtracting the amount of the carboxyl groups from the sum of the amounts of the basic groups and the phenolic hydroxylic groups is larger than 0.60, wherein the amount of the above-mentioned functional groups is expressed by milliequivalent/g of the product.The novel porous and spherical carbonaceous product having its groups in the above-mentioned relationships exhibits a specific adsorptive capability in living bodies and particularly useful as a pharmaceutical for treating diseases of the liver and kidney after administered orally.
