ABSTRACT:
Disclosed herein are a sorbent comprising spherical particles of activated carbon formed from a pitch and/or a synthetic, organic high polymer, to which a non-crystalline compound of zirconium has been deposited in an amount of 1 to 10% by weight (calculated as ZrO.sub.2) to the weight thereof and a process for preparing the sorbent comprising the steps of impregnating the spherical particles of activated carbon with an aqueous solution of a water-soluble compound of zirconium and after treating the thus impregnated spherical particles of activated carbon with an alkali, thermally treating the thus treated spherical particles of activated carbon at a temperature of 400.degree. to 1000.degree. C.
