Abstract:
1. A method of producing an orally administered adsorbent, comprising the steps of: preparing spherical particles of a furfuryl alcohol resin through a self-condensation reaction of furfuryl alcohol in the presence of an acid catalyst and a protective colloid and curing of the self-condensation reaction product; obtaining spherical particles of carbon by carbonizing the spherical particles of the furfuryl alcohol resin at a temperature of 400-900° C.; and forming spherical particles of activated carbon by activating the obtained spherical particles of carbon at a temperature of 700-1000° C., wherein the adsorbent has an average particle diameter of 150-1000 μm and a specific surface area of 1000-1800 m
