Ultra-fast adsorption of four typical pollutants using magnetically separable ethanolamine-functionalized graphene

• The magnetically separable ethanolamine-functionalized graphene was synthesized. • The Fe 3 O 4 and AE co-modified graphene (MAEGO) can achieve ultra-fast adsorption. • In only five minutes, the adsorption capacities of MAEGO for TC is 315.25 mg/g. • MAEGO can remove tetracycline, levofloxacin, methylene blue, methyl orange rapidly. • When the adsorption of TC reached equilibrium, the removal rate was 97.80%.
