Problems solved by technology

Although the air purifier containing bamboo vinegar obtained by the invention has a certain antibacterial ability, the bamboo vinegar is volatile, unstable antibacterial activity, and has a single purification function
[0007] In summary, the air purifiers of the prior art have a single function, and the bamboo vinegar added in the air purifiers has the disadvantages of being volatile or unstable in antibacterial activity. Therefore, a multifunctional, non-volatile, stable performance is developed. High-efficiency antibacterial compound air purifier has important significance

Abstract

The invention provides a multifunctional air purificant and a preparation method. The method comprises the following steps: modifying macroporous polystyrene-divinylbenzene adsorption resin with chloromethylation and acidic groups, then loading a silver-doped titanium dioxide photocatalyst on the surface of acidic adsorption rein, and then mixing the acidic adsorption rein with refined bamboo vinegar, chitosan and glycerol to obtain the multifunctional air purificant. Compared with a traditional method, the multifunctional air purificant prepared with the preparation method disclosed by the invention has the advantages that on the one hand, the multifunctional air purificant has good adsorption and catalytic degradation capacity on volatile organic compounds in air; on the other hand, themultifunctional air purificant has a good inhibiting effect on bacteria and fungi in the air; in addition, the added bamboo vinegar is not easy to volatilize and stable in bacteriostatic activity.
