Columnar activated carbon is a kind of multi-purpose adsorption material, and the scope of application does not need to be described. However, the wide promotion of columnar activated carbon is inseparable from its strong adsorption capacity.
As water purification activated carbon, the strong adsorption capacity of columnar activated carbon mainly comes from the activated carbon pores, and a large number of pores constitute a strong adsorption capacity and storage space.
Adsorption is a process in which a substance attaches to the surface of another substance. The strong adsorption capacity of columnar activated carbon is mainly based on three adsorption principles:
Physical adsorption: the common adsorption method of columnar activated carbon. The molecules in the inner space of columnar activated carbon attract each other with the molecules on the adsorbed substance, resulting in adsorption capacity.
There are a small number of molecules in the pores of the columnar activated carbon. The molecules and molecules can attract each other, so that they can adsorb impurities and suspended solids in the sewage, and adhere to the surface of the columnar activated carbon.

Chemical adsorption: The molecules between the adsorbed substance and the adsorbed substance have a certain amount of positive and negative charges. Due to the mutual attraction between the charges, chemical bonding forces are generated, and the molecules will undergo chemical changes to produce adsorption capacity.
Ion exchange adsorption: The electrostatic attraction on the adsorbed material is concentrated on the surface of the columnar activated carbon, so that the adsorption capacity is generated and the material is adsorbed.

A variety of forces can be generated during the adsorption process, which influence each other to adsorb each other, thus ensuring the adsorption capacity of the columnar activated carbon.
The more developed the pores and the larger the pore space, the stronger the adsorption capacity of the columnar activated carbon, and the lighter it is in the hand. This can also be used as a basis for purchasing columnar activated carbon.
