Phosphate ion adsorbent comprising activated carbon, method for producing the same, and phosphate ion adsorbing method

摘要

PPROBLEM TO BE SOLVED: To effectively reuse a waste phenolic resin to be an industrial waste material aiming at development of a novel adsorbent that a phenolic resin is carbonized and activated by focusing attention on the formability of the adsorbent by carbonizing and activating the phenolic resin. PSOLUTION: The adsorbent made of an activated carbon making the waste phenolic resin as a raw material comprises the activated carbon having a BET specific surface area of 460 mSP2/SP/g or larger, and the yield of the activated carbon of 26 wt.% or higher. A process for producing the adsorbent made of the activated carbon comprises the steps of making the waste phenolic resin as the raw material, carbonizing it at 600 to 800C and then activating this carbonized material at 1,000C or higher.
