As we all know, the activated carbon filter equipment in all areas of life we can play a good role, because of its special properties make it widely used in our lives, so we take a look at this device In all aspects of the adsorption principle!
Surface adsorption
Activated carbon as a solid adsorbent solid adsorbent sampling promulgated by the U.S. Occupational Safety and Health (NIOSH), accounting for 31.0%, the 3rd edition of the Workplace air monitoring test methods published in 1990, accounting for 36.1%; 2003 Workplace air monitoring test methods published version 4 accounted for 50.0%, up a solid adsorbent applications. The activated carbon adsorption is able to produce, mainly due to atomic force field on the solid surface is non-saturated, surface energy, and thus can absorb certain molecules in order to reduce the surface energy.
Second, on the solid adsorption
Experts believe that the chemical adsorption is always limited to a single molecular layer adsorption, the released heat of adsorption is approximately the chemical reaction heat, generally greater than 45 kJ / mol, and with selective adsorption, this is because the role of strongly chemically. The p hysical adsorption of the van der Waals force is generally a multi-molecular layer, the heat of adsorption is generally less than 25kJ/mol adsorption effect only in the vicinity of the boiling point of the adsorbed matter was very significant. At a certain temperature the pressure exceeds 0.01p/p0 when can the apparent adsorption effect, the formation of a saturated monolayer adsorption pressure in the range about about 0.1p/p0.
Gas molecules touch elastic collision only touch in the blank on the solid surface, only to be adsorbed on the solid surface has been adsorbed gas molecules, i.e. adsorption is a monomolecular layer. The probability not subject to the influence of the surrounding gas molecules, gas molecules are adsorbed to jump back to the gas phase from a solid surface that does not consider the interaction forces between the gas molecules is established. The improvement is that the surface layer of molecules adsorbed, due to van der Waals forces, the gas itse lf, re-adsorbed molecules form a second layer, the third layer, or even more of the adsorption layer, and do not have to wait until the first layer adsorption full after multilayer adsorption, adsorption and desorption of dynamic equilibrium exists between the layers.felt fabric
