Fe-Mn-Ce metal oxides (FeMC) were prepared by using a co-precipitation method for the removal of tetracycline (TC). The FeMC composite has a good adsorption performance, and the maximum adsorption capacity at 318 K is 307.692 mg/g. FeMC metal oxides maintain good stability, and the removal rate of TC still reaches 85.24% after 5 cycles. The structural characteristics and adsorption mechanism of FeMC adsorbent have been systematically studied. According to the study of adsorption kinetics and adsorption isotherms, the adsorption process conforms to the quasi-secondorder kinetic model. Langmuir isotherm model is more suitable than Freundlich isotherm model to describe the adsorption equilibrium data. The Fourier-transform infrared spectrum shows that the adsorption between FeMC and TC is realized by the stretching vibration of C-H and the stretching vibrations of C-O or C-O-C.
