Respiratory problems in the general industrial environment are the key, and protective equipment is naturally indispensable. Similar gas masks, dust masks, air respirators, etc. are all common protective measures and are one of the tools we can't live without.
The adsorbent layer of the gas mask is activated carbon loaded with a catalyst or a chemical sorbent. This activated carbon is commonly referred to as impregnated activated carbon or impregnated carbon, or as anti-toxic carbon or catalytic carbon. Impregnated activated carbon has the following three effects to achieve anti-virus.
1 Physical adsorption. Physisorption occurs due to the attraction between the adsorbate and the adsorbent molecules. The adsorbed molecules retain their original chemical properties. They are non-selective and have a fast adsorption and desorption rate. For example, activated carbon for sarin, mustard gas, and chlorine The poisonous agent vapor is physical adsorption.
2 Chemical adsorption. Chemisorption occurs when the adsorbate and the adsorbent molecules absorb with similar chemical chain forces. The adsorbate forms a surface compound with the adsorbent, which is selective and usually irreversible.
