The application provides a porous carbon material for adsorbing heavy metals and a preparation method and application thereof, and relates to the technical field of adsorbent preparation. The preparation steps of the porous carbon material include: S1, stirring hydrochloric acid dopamine and N-hydroxymethyl acrylamide in anhydrous ethanol, adding concentrated sulfuric acid for reaction, filtering, and washing until neutral to obtain DTA; S2, adding acrylamide, acrylonitrile, acrylic acid and 3-(acrylamidomethyl)-5-benzoyl-4-hydroxy-2-methoxybenzenesulfonic acid into water to obtain a solution system, adding sodium hydroxide, the intermediate product DTA and 2-hydroxy-4-(2-hydroxyethoxy)-2-methylbenzophenone in sequence, carrying out ultrasonic treatment, irradiating under a mercury lamp light source, washing, and freeze-drying to obtain PAAAS-D; and S3, carrying out carbonization of the PAAAS-D after pre-oxidation treatment under a inert atmosphere to obtain CPAAAS-D. The porous carbon material has rich active sites and an optimized pore structure, and can efficiently adsorb Fe, Co and Ni heavy metal ions.
