Can electrostatic technology be used to adsorb pm2.5?

Haze weather has gradually become the main factor affecting the external air quality in autumn and winter in central and eastern China, and the occurrence of haze is closely related to fine particulate matter (PM2.5). The concentration of PM2.5 in haze weather is significantly higher than that in non-haze weather, indicating that the increase of PM2.5 concentration is one of the important reasons for haze. PM2.5 seriously affects air quality and public health. Particles in the air are called. Below 5.952? 5 aerodynamic particles. It is also a part of the total suspended particulate matter (TSP) in the atmosphere and an air pollutant with important health significance.

Compared with atmospheric coarse particles, fine particles have smaller particle size and larger relative surface area, and can adsorb a large number of toxic and harmful substances, such as heavy metals, acid oxides, polycyclic aromatic hydrocarbons, bacteria and viruses. It stays in the atmosphere for a long time and has a long transportation distance, which has great influence on human health and atmospheric environmental quality. The smaller the particle size, the deeper it enters the respiratory tract. It is usually deposited in the upper respiratory tract, while 2.5 can penetrate into bronchioles and alveoli, and may enter the blood circulation, leading to the decline of lung function, affecting the incidence of respiratory system and cardiovascular diseases, the number of inpatients and the mortality rate of the population. In foggy weather, the public should wear masks and take necessary protective measures.
