ATP-Fe3O4-APTES (AFAS), was synthesized by modifying magnetic attapulgite with 3-aminopropyltriethoxysilane to remove U(VI) and tetracycline (TC) from medical wastewater. In a single-component system, the maximum adsorption capacities of AFAS for U(VI) were 298.87 mg/g and tetracycline were 111.71 mg/g, respectively. Synergistic effect instead of competitive adsorption occurred between U(VI) and TC under the combined binary system, with the complexation interactions between the U(VI) and TC. U(VI) adsorption mechanisms on AFAS (e.g. precipitation, ion exchange and complexation) are different f...
