Abstract：In order to obtain a catalyst with high performance,simple preparation and easy recovery,a magnetic composite catalyst Co-Fe3O4/α-FeOOH was synthesized by one-step atmospheric aging method.Trimethoprim(TMP)was used as the target pollutant.According to the removal effect of TMP by advanced oxidation system,the optimum preparation conditions of the material were determined.The results show that the optimum preparation parameters of Co-Fe3O4/α-FeOOH catalyst are as follows:Co2+doping ratio is 3％,aging temperature is 100℃ and reaction time is 8 h.Based on the characterization analysis of composition and morphology,the material is composed of rod-like α-FeOOH and granular Fe3O4 with mesoporous structure.The average pore size is 11.59 nm and the specific surface area is 54.64 m2/g.It has good crystallinity and high purity,and the three elements of Fe,Co and O are evenly distributed.The saturation magnetization of the material is 14.45 emu/g.
