Ventilation: the best way is ventilation. Therefore, we must take appropriate measures to reduce the content of formaldehyde
2, plant absorption method: plants have a strong ability to absorb formaldehyde, such as cactus, chlorophytum, reed, ivy, Cycas, chrysanthemum, etc. . In general, large leaf and vanilla plants absorb formaldehyde better, such as chlorophytum, hultail, etc.
3. folk soil spreading method: tea residue, pomelo peel, onion slices and pineapple pieces are placed in the newly decorated room or the whole room is fumigated with white vinegar.
4, activated carbon adsorption method: solid activated carbon has the characteristics of porous, formaldehyde and other harmful substances have a strong adsorption and decomposition, the smaller the particles of activated carbon adsorption effect is better.
5, photocatalyst decomposition method: photocatalyst in the catalyst under the stimulus of light, and oxygen and water in the air to generate negative ions and hydroxide radicals, can oxidation and decomposition of various organic pollutants and inorganic pollutants, and finally degraded into carbon dioxide, water and the corresponding acid and other harmless substances, so as to achieve the role of decomposition of pollutants, air purification.
6, chemical purification method: at present, the market formaldehyde capture agent is divided into two kinds, one is through the neutralization of formaldehyde, produce harmless substances to purify the air; The other is to purify the air by blocking formaldehyde and preventing it from volatilizing.
