1.Depending on its own pore structure
Activated carbon is a kind of microcrystalline carbon material which is mainly made of carbonaceous material with black appearance, developed internal pore structure, large specific surface area and strong adsorption capacity.Activated carbon material has a large number of invisible micro pores, 1 g activated carbon material micro pores, will be expanded after the surface area can be up to 800-1500 square meters, the use of.That is, the internal surface area of the pores in an activated carbon particle the size of a grain of rice could be the size of a living room.It is these highly developed, such as human capillary pore structure, so that activated carbon has a good adsorption performance.
Activated Carbon Adsorption is the act of an accumulation of a gas or liquid onto the surface of the activated carbon, an inert solid material. This process is used to remove diverse, dissolved contaminants from water, air, and gaseous streams.
2. The force of adsorption between molecules
Also known as “van der Waals gravity”.Although the speed of molecular motion is influenced by temperature and material, it is always moving in the microenvironment.activated carbon due to the mutual attraction between molecules, when a molecule was activated carbon inner hole capture into the activated carbon inner pore, due to the mutual attraction between molecules, will lead to more molecules are attracted, until the fill activated carbon inner pore.
Activated carbon adsorption principle: Formed in the particle surface layer balance the surface concentration, then the impurities of organic substances adsorbed to activated carbon particles, the initial high adsorption effect. But over time, activated carbon adsorption capacity will be weakened to varying degrees, the adsorption effect also decreases.If the aquarium water turbidity, high organic content in water, activated carbon will soon be the loss of filtration function. The activated carbon should be regular cleaning or replacement.
