Magnetic MIL-101（Fe）/CoFe2O4 and MIL-101（Fe）/NiFe2O4 composites were synthesized by a simple solvothermal method.The composite phase structure,morphology,magnetic properties and adsorption properties were investigated by X-Ray diffractometer（XRD）,scanning electron microscope（SEM）,vibrating magnetometer（VSM）,thermal gravimetric analyzerand（TGA） and UV-vis spectrophotometer（UV）,etc.The magnetic metal organic framework was used to adsorb Rhodamine B,and the effect of initial concentration on the adsorption capacity of Rhodamine B was studied.The results showed that the prepared magnetic metal matrix composites had uniform morphology,high crystallinity and high saturation magnetization.The composite had the double advantage of metal-organic skeleton material and magnetic material.MIL-101（Fe）/CoFe2O4 had higher adsorption capacity to Rhodamine B（97.3 mg/g）.Thermodynamic study showed that the adsorption isotherm equation accorded with Langmuir model,and the adsorption kinetics study showed that the adsorption mechanism was related to the adsorbates and adsorbents.Magnetic metal-organic framework nanocomposites would have broad application prospects as sewage treatment agents.
