Shenyang activated carbon adsorption principle harmful gases

Respect for adsorption of harmful gases activated carbon adsorption This is life in the city is no stranger. Now that people place more emphasis on the environmental pollution, all want to live in clean, fresh air among so many businesses spotted the market, the introduction of harmful gases absorb a wide variety of products. By actual proof, activated carbon adsorption for the effect of all the products which harmful gases significantly. Now we are many interpretations of activated carbon adsorption principle of harmful gases. Before multifaceted interpretation of activated carbon adsorption principle harmful gases, we start to understand a technical term: molecular kinetic theory. Molecular dynamic content theory is: the object is composed of a large number of molecules; molecular unceasing doing random motion; there is interaction of attraction and repulsion between molecules. As for the molecular kinetic theory of content Detailed. The object is composed of a large number of molecules: Number of molecules consisting of "substantial" and molecular "small" is corresponding. Molecular unceasing doing random motion: through diffusion and Brownian motion is the random movement of molecules macro expression. Molecular motion more intense, the higher the temperature of the object, it is called "thermal motion." The existence of an interaction between the molecules of attraction and repulsion: repulsion and gravity exist simultaneously, and both with increasing distance r decreases between molecules, but more sensitive to gravitational repulsion than the r value. So when r is less than a certain value r0 (ie equilibrium position), the force of repulsion between the molecules behave; when r is greater than r0, showed intermolecular force of gravity. Activated carbon is made of a carbon-containing material is developed internal pore structure, large surface area, strong adsorption capacity in all microcrystalline carbonaceous material. We know in our physical molecules are invisible to the naked eye, but can be viewed by the scientific tools to pore surface area of ??activated carbon is very large, one gram of microporous activated carbon surface area of ??up to 700-2300 meters. Figuratively speaking, with the grain size of the activated carbon, the surface area of ??micropores can we live with a large living room area of ??the wall to be compared. It is because of the relatively large area of ??microporous activated carbon, combined with molecular kinetic theory principles mentioned above, we will know the super activated carbon adsorption capacity. But not all objects as long as it has a large area micro super adsorption ability of harmful gases, the properties of harmful gases, only the pore diameter greater than 0.45nm and smaller than 2.0nm to suck be harmful gases. The porosity is reached to the activated carbon pore diameter greater than 0.45nm to less than 2.0nm on more than 90% of the total porosity. Since the activated carbon is a physical adsorption, so it will not produce secondary pollution, thereby identifying the absorption of harmful gases supremacy.
