摘要（英）：

The invention relates to a preparation method of a modified Fe3O4/lanthanum doped barium ferrite adsorption material. The preparation method comprises the following steps: (1) preparing modified Fe3O4nano-particles; (2) preparing a lanthanum doped barium ferrite adsorption material; (3) dissolving 1-10 mol parts of the lanthanum doped barium ferrite adsorption material and 1 mol part of the modified Fe3O4 nano-particles in 80-110 mol parts of distilled water to obtain a mixed solution; and (4) performing continuous ultrasonic oscillation on the mixed solution for 3-7h, performing suction filtration, and then, performing drying for 6-24h in a vacuum drying oven at 80-150 DEG C to obtain the modified Fe3O4/lanthanum doped barium ferrite adsorption material. The preparation method of the modified Fe3O4/lanthanum doped barium ferrite adsorption material, disclosed by the invention, improves the magnetic energy of unit ferrite and enhances the adsorption capacity to heavy metal ions, and the adsorption rate reaches up to 99.1%.
