Activated carbon supported macroporous adsorbent resin and preparation method thereof

The invention discloses activated carbon supported macroporous adsorbent resin and a preparation method thereof. By the aid of a stable framework of resin, activated carbon is supported to the resin framework by an organic carbon source, and adsorptive selectivity of the prepared macroporous adsorbent resin is improved; besides, the organic carbon source is adopted as an activated carbon raw material in a preparation method, so that the problem of a harsh preparation environment caused by powdered activated carbon is solved. The preparation method comprises steps as follows: an oil phase obtained after mixing of monomers, a cross-linking agent and a pore-forming agent is added to an aqueous phase, a resin ball is obtained by synthetic extraction with a suspension polymerization method, then the organic carbon source is adsorbed to the resin ball by column chromatography, and after a high-pressure hydrothermal reaction, activated carbon is supported to the resin framework and the macroporous adsorbent resin is
