The invention provides a sustained-release drug intercalation magnetic houghite which has the fluorescence lighting performance, and a preparation method. A salt liquid is prepared by the mixture of a magnetic stroma, bivalent metal salt and trivalent metal salt; a lye prepared by NaOH and Na2CO3 is prepared into CO3-LDH/Fe3O4; the dried CO3-LDH/Fe3O4 is baked for 2h at the temperature of 450 DEG C to form a double-metal oxide; under the protection of N2, the double-metal oxide obtained by baking is put in a container filled with an amoxicillin sodium lye; finally the mixture is put into a constant temperature oscillator to be oscillated for 24h at the speed of 180r/min, then filtered, washed and dried to obtain the sustained-release drug intercalation magnetic houghite which has the fluorescence lighting performance and has a chemical formula: [M(II)<1-x>M(III)(1-Beta)xM'(III)Betax(OH)2](AMX<->)a(A)b question mark mH2O/Fe3O4. The invention has the advantages of removing the inorganic ...

The invention provides a preparation method of a magnetic composite oxide and the application of the oxide for serving as an adsorbent of negative ion pollutants. FeSO4 question mark 7H2O and Fe2(SO4)3 question mark XH2O are used for preparing a magnetic medium; an alkali liquor that is prepared by the magnetic medium, divalent metal ions, trivalent metal ions, NaOH and Na2CO3 is prepared into a magnetic houghite precursor; and the magnetic houghite precursor is baked to obtain a baked magnetic composite oxide. The baking product of the magnetic houghite precursor that is obtained by the preparation method is used for absorbing the negative ion pollutants in water bodies, has higher absorbing capacity, and can be easily separated and recycled after adsorption.
