Description
Technical field
The present invention relates to technical field of biological material, especially relate to a kind of preparation method for airfiltering carbon aerogels。
Background technology
According to estimates, annual 1600000 people of China are dead because of air pollution, account for the 17% of the total death toll of China。" global disease bears 2010 annual reports " is estimated, within 2010, China result in 1,200,000 people's premature death because outdoor PM2.5 pollutes。This report also claims, and PM2.5 affects the fourth-largest risk factor that China Public is healthy, and front three is unhealthy diet, hypertension and smoking respectively。In " lancet " report, estimate that dead person's number morning that China causes because of outdoor air pollution every year is 350,000 ~ 500,000 people。Research finds, the average annual PM2.5 of China is 52 μ g/m3。On the whole, the air " unhealthy " (> 55 μ g/m3) that the Chinese of 38% breathe。Additionally, for the discharge of NO2 and SO2, have 15% ~ 25% to come from transportation emission, 30% ~ 50% comes from the fire coal in power plant, also has 25 ~ 35% from factory。Wherein it is concentrated mainly in the monitoring to six kinds of pollutant: PM2.5, PM10, SO2, NO2, O3 and CO。
Refer to the diameter particulate matter less than or equal to 2.5 microns in air, also referred to as lung particulate matter can be entered, air quality and visibility etc. are had important impact。PM2.5 particle diameter is little, and rich in substantial amounts of poisonous and harmful substances, and time of staying length, fed distance in an atmosphere is remote, thus the impact of health and atmosphere quality is bigger。
In recent years, environmental pollution grows in intensity, and air pollution and water pollution are especially prominent, have a strong impact on health, takes the multiple technologies such as phytoremediation, photocatalysis, biodegradation, absorption for improving present situation。By contrast, adsorption technology has the advantages such as economy, environmental protection, convenient, non-secondary pollution。Aerogel material has nano-porous structure, and aperture is adjustable, and specific surface area may be up to 1000 ~ 2000m2/g, and its density is extremely low, is three times of air, is also the lightest known in the world solid。The characteristics such as aeroge is ultralight with it, porous receive much concern at present, obtain very big progress in physics, chemistry, biology etc.。Carbon aerogels application in capacitor, water pollution process etc. receives much concern, owing to carbon aerogels has the characteristic of loose structure, therefore it is used to process water pollution and obtain important breakthrough in this field, and in air cleaning (especially fine particle process), there is no system documentation report。
