The adsorption is reversible, since the molecular thermal motion will be in the adsorption of the adsorbed together from solid appearance, this phenomenon is called desorption。 Physical adsorption can be used to form single molecule adsorption layer or multi molecule adsorption layer。 Because the intermolecular force is ubiquitous, an adsorbent can adsorb a variety of substances, but because the adsorbate (solute) properties are different, the amount of adsorption is also different。 This adsorption image is closely related to the appearance of the adsorbent and the distribution of pores。

chemical adsorption

The chemical bond between adsorbent and adsorbate (solute) results in chemical reaction, which makes the adsorbent and the adsorbate (solute) linked together firmly. Because the chemical reaction requires a lot of activation energy, it usually needs to be carried out at higher temperature, and the adsorption heat is larger. Chemical adsorption is a selective adsorption, that is, an adsorbent only has adsorption effect on some or several kinds of substances. Because the chemical adsorption is carried out by the adsorbent and the adsorbate direct chemical bond force, so can only form a single chemical adsorption in adsorption layer is relatively stable, not easy desorption, surface chemical properties of adsorption and adsorption of the agent directly, relevant chemical properties and adsorption.

AC adsorption

The ion of a substance is concentrated at the charged point on the surface of the adsorbent due to electrostatic attraction。 In the adsorption process, it is accompanied by the exchange of equal ions, that is, the adsorption of an adsorbate (solute) ion。 The adsorbent has to release an equal amount of ion, that is, ion exchange。化学反应器吸附器 The charge of ions is the decisive factor of AC adsorption。 If the adsorbate (solute) concentration is the same, the more ions charge, the stronger the adsorption force is on the reverse charge point of the adsorbent surface。
