Abstract | The invention relates to a magnetic nano-ore composite material for efficiently removing thallium and a preparation method and application thereof. The composite material is prepared from kaolin and ferrous sulfate through an impregnation method and a ferrite program under the normal-temperature and alkaline conditions, and the method comprises the following steps: 1, impregnating kaolin obtained after vacuum drying in a ferrous sulfate solution, and uniformly stirring in a closed environment; and (2) blowing air into the mixed solution, continuously aerating, adding a NaOH solution into the mixed solution during aeration to stabilize the pH value at 8.0-10.5, and continuously reacting to obtain the magnetic nano-ore composite material which is used for removing the thallium element in the water body through adsorption reaction. Compared with the prior art, the composite material has the advantages of wide application range, simple and feasible reaction conditions, capability of adsorbing thallium in water at |
