The invention provides a carbon-base loaded adsorbent for removing heavy metal in wastewater and a preparation and use method thereof. The carbon-base loaded adsorbent for removing heavy metal in wastewater comprises ammonified graphene oxide carriers, wherein titanium dioxide and ferroferric oxide are loaded on the ammonified graphene oxide carriers. The powder or particle adsorbing material loaded with titanium dioxide and ferroferric oxide prepared by the invention and taking ammonified graphene oxide as the carriers can efficiently adsorb heavy metal ions in wastewater, can effectively degrade organic pollutants in wastewater and can be efficiently and quickly recovered by using the magnetism of ferroferric oxide. The harm of the heavy metal ions in wastewater to water bodies is greatly reduced, the load of purifying the water bodies through organic matters is reduced, and the feasibility and convenience in carbon-base material recovery operation after wastewater treatment are increased.
