| titleOfInvention | A kind of preparation method of iron-based hydrotalcite |
| abstract | The invention discloses a preparation method of iron-based hydrotalcite. In the method, ferrous salt is directly used as raw material, and ferrous salt is mixed with Mg 2+ , Zn 2+ , Cu 2+ , Ni 2+ , Co 2+ , Ca Soluble salts such as 2+ and Mn 2+ can be oxidized by air or oxygen at a pH of 5.5 to 10.5 to obtain iron-based hydrotalcite. The preparation process of the present invention is simple, the reaction conditions are mild, the sources of Fe 3+ raw materials are extensive and cheap, the obtained iron-based hydrotalcite has a high degree of crystallization, and the crystal phase and particle size are uniform, and in the hydrotalcite prepared by the present invention, except metal Fe, other The amount of the metal in the hydrotalcite laminate can be much lower than the traditional method, and the metal molar ratio of the divalent metal raw material (Ni, Co, Cu, Zn, etc.) to the Fe 3+ raw material in the Fe 3+ based hydrotalcite prepared by the traditional method Generally, hydrotalcites can only be synthesized if they are greater than 2, and the method of the present invention can reduce the raw material ratio to 0.1, and can be used to synthesize hydrotalcites doped with other positive divalent metal elements in low molar ratios. |
