What is the activated carbon CTC value

The CTC value of activated carbon is an index to measure the adsorption capacity of activated carbon. CTC is an abbreviation of the English word "Cation Exchange Capacity", meaning anion exchange capacity, which is usually used to describe the ability of activated carbon to exchange ions with water.

In the manufacturing process of activated carbon, the raw material is calcined and activated to produce a large number of tiny holes and active sites on its surface, so that it has a strong adsorption capacity. The higher the CTC value, it means that the activated carbon can absorb more ions and other impurities in the solution.

Activated carbon is widely used in water treatment, air purification, food processing and other fields. In water treatment, activated carbon improves water purity and taste by absorbing chemical pollutants, organic matter and chloramines in water. In air purification, activated carbon can absorb harmful gases and odors in the atmosphere to keep the air fresh and healthy. In food processing, activated carbon is often used as a bleach and odor remover to make food more beautiful and healthy.

In short, the CTC value of activated carbon is an important parameter to evaluate the adsorption capacity of activated carbon, and its application in various fields is more and more extensive. With the progress of science and technology and people's attention to health, the application prospect of activated carbon will be more and more broad.
