Abstract

The invention relates to a method for preparing a PM2.5 (particulate matter 2.5) and TVOC (total volatile organic compound) purification biological absorbent from plant waste materials. The method mainly solves the technical problems of easy absorption saturation, easy furniture corrosion and the like of the existing method for purifying room PM2.5 and TVOC. The method provided by the invention has the technical scheme that the method for preparing the PM2.5 and TVOC purification biological absorbent from the plant waste materials comprises the following concrete steps of (1) processing raw materials; (2) performing rinsing and drying; (3), performing alkali soaking and water bath; putting 1 to 3 weight parts of dried plant waste materials into 3 to 9 weight parts of NaOH solution with the concentration being 0.10 mol/L to 0.30 mol/L to be soaked for 30min to 90 min; then, putting the soaked plant waste materials into a 60 DEG C to 100 DEG C constant-temperature water bath pot to be subjected to water bath for 30 min to 60 min; (4) performing flushing; (5) performing drying; (6) performing crushing and sieving: crushing the dried plant waste materials by a crushing machine; sieving the materials by a sieve being 40 to 100 meshes; obtaining the biological absorbent.

Description

technical field [0001] The invention relates to a method for preparing a biosorbent for purifying PM2.5 and TVOC by using plant waste, which belongs to a production method of an environmentally friendly and original ecological green biosorbent. Background technique [0002] In recent years, the pollution of PM2.5 in the air has attracted the attention of all walks of life. People can clearly recognize the inconvenience that PM2.5 brings to life and health in daily life. Domestic and foreign studies have also fully proved that PM2.5 has a significant impact on fertility and health. Therefore, the research on PM2.5 and its governance is not only imminent, but also far-reaching. PM2.5 is solid or liquid particulate matter with a diameter less than or equal to 2.5 microns. Its sources are complex, including both natural and human factors. Human factors are the main source of emissions. Natural factors include wind-blown dust, sea salt, plant pollen, fungi, bacteria, and pollu...
