Problems solved by technology

Decomposition air purifier is an air purifier with TiO 2 Substances that can produce hydroxyl radicals and superoxide radicals with oxygen or water molecules under the irradiation of sunlight. Hydroxyl radicals and superoxide radicals have strong redox capabilities, which can oxidize harmful substances in the air Decomposition, the advantage of this type of air purifier is that it can oxidize and decompose the pollutants in the air, but the disadvantage is that the band gap of titanium dioxide reaches more than 3.0, and this kind of redox reaction can only be carried out under ultraviolet light

preparation example Construction

[0050] The preparation method of concrete Robinia pseudoacacia extract is as follows:

[0051] 1. Blend the leaves of Robinia pseudoacacia, Robinia pink and Robinia safflower in a weight ratio of 0.5:0.8:1.2, wash and chop, then moisten with ammonia water, add ethanol, and reflux for 1 -3 hours, filtered while hot, concentrated to no ethanol, and obtained the leaf extract of Robinia pseudoacacia.

[0052] 2. Blend the flowers of Robinia pseudoacacia, Robinia pink and Robinia safflower according to the weight ratio of 0.5:0.8:1.2, wash and chop, add honey, reflux for 1-3 hours, and keep warm Filtrate, concentrate until there is no ethanol, and obtain the flower extract of Robinia pseudoacacia.

[0053] 3. Blend the extracts of leaves and flowers of Robinia pseudoacacia in step 1 and step 2, add ethanol, stir ultrasonically for 2.5 hours, and concentrate until there is no ethanol to obtain the extract of Robinia pseudoacacia.

Embodiment approach

[0056] As an embodiment of the present invention, the neem extract is extracted by mixing neem bark, neem seeds and neem flowers in parts by weight of 1.2:0.5:0.8.

[0057] Neem bark is the dry root bark and bark of neem, stripped in spring and autumn, dried, or remove the rough bark, dried, also known as neem bark, bark of neem branches, white bark of neem tree, eastbound neem root white bark, neem bark Neem bark, neem root bark, neem root bark, neem root bark. The main components in neem bark are triterpenoids, flavonoids, and phenolic compounds. The triterpenoids in neem bark mainly include: neem terpene ketone lactone, neem terpene alcohol lactone, neem terpene ketone, neem terpene acid methyl ester, neem porin A, neem poling B, arginine, Geyou Ning, neem triol and so on.

[0058] In addition to triterpenoids, neem bark also contains some other compounds, such as: tetracosyl ferulate, pentapentyl ferulate, hexacyl ferulate, Heptalyl, Octacyl Ferulate, Sitosterol, Stigma...

Description

technical field [0001] The present invention relates to an air-purifying composition, in particular to an air-purifying composition containing plant extracts, and further relates to the B01D field. Background technique [0002] With the gradual improvement of living standards, the quality of the air environment is gradually decreasing, and the requirements for air purification are getting higher and higher. There are three principles of air purification at this stage: adsorption type, covering type and decomposition type. Adsorption-type air purifiers use physical adsorption, chemical adsorption, oxidation, catalytic oxidation, and reduction properties similar to activated carbon to remove pollutants in the air. The disadvantage of this type of air purifier is that it cannot be used for a long time, and the air purifier needs to be replaced regularly. At the same time, the pollutants are still pollutants and have not been further decomposed into inorganic substances. Cover...
