The adsorption mechanism of activated carbon
Activated carbon is increasingly used in life because of its extremely good adsorption capacity. So what is the ability to subjugate? What is the adsorption mechanism of activated carbon? Let’s find out with Vina TS
Adsorption, in chemistry, is the process that occurs when a gas or liquid is attracted to the surface of a porous solid or to an increase in its concentration on the surface of another substance. The gas or vapor is called the adsorbate, the porous solid used to absorb the gas or vapor is called the adsorbent, and the gas that is not adsorbed is called the inert gas. The reverse process of adsorption is called desorption or desorption.
There are two adsorption processes: physical adsorption and chemical adsorption.
It is difficult to distinguish between physical adsorption and chemical adsorption, sometimes it is carried out in parallel, and sometimes there is only a physical adsorption phase depending on the properties of the surface of the adsorbent depending on process conditions (temperature, pressure, etc.)
Surface image of activated carbon
Activated carbon is an amorphous carbon produced by activating materials with high carbon content such as (bamboo, rice husk, wood, and coconut shell…) under anaerobic conditions, high pressure, and high temperature. As a result, the structure of the coal becomes porous, hollow fiber, including thousands of tiny pores, small in size to help increase the contact surface area in the reactions. The larger the activated carbon surface area, the stronger the attraction.
For water: When the water flows through the activated carbon surface, impurities, dirt, metal ions and contaminants such as chlorine, benzene, grease, etc. will adhere to the carbon surface. Therefore, in addition to the effect of filtering activated carbon water, it also has a decolorizing effect.
– In-home water purifiers, there are filters with activated carbon, after a period of use, it is necessary to replace the filter core to ensure the best water quality.
– In industrial production, the adsorption mechanism is also used to treat industrial wastewater or some stages in production.
For the air: When the air flows through the surface of the activated carbon, harmful dust and gases such as SO2, CO2, H2S … will be trapped, and the output is non-adsorbable gases such as Oxygen, Ni -to… That’s why activated carbon is used in air purifiers.
