| titleOfInvention | Preparation method of aqueous nano antibacterial photocatalytic titanium oxide composite sol |
| abstract | The invention relates to a preparation method of aqueous nano antibacterial titanium oxide composite sol, which comprises the following steps: (1) acid hydrolysis; (2) purifying titanium liquid; (3) titanium peroxide complexation; (4) and (4) catalytic decomposition. According to the preparation method, the cheap ilmenite is used as the raw material, and the titanic acid is obtained without alkali precipitation of titanyl sulfate. According to the method, zinc peroxide is used as a reaction substance, the complex formed by peroxide and titanium ions is directly dissolved in water, secondary purification and dissolution are not needed, and zinc sulfate formed by Zn ions and sulfate radicals has an antibacterial and deodorizing effect and is simple and convenient to step; at the same time, by introducing Fe 2+ As a Fenton catalyst, the titanium peroxide is quickly decomposed to generate titanium oxide, so that the titanium peroxide is prevented from being gelatinized, and a composite antibacterial product is formed with zinc sulfate. The prepared compound product has uniform particle appearance, can greatly save the use of alkali and the discharge of waste water, and the preparation method has simple process and is suitable for large-scale industrial production. |
