  Columnar activated carbon has many different shapes and pores of different sizes, large specific surface area, and strong adsorption capacity. Therefore, columnar activated carbon is often used to remove pollutants in water, purify air, and recover waste gas.

   

  The chemical properties of columnar activated carbon are due to the fact that the surface of activated carbon contains oxides and complexes. coconut shell charcoal powder price Some of these substances are derived from raw materials, and some are generated due to the effect of air or water vapor during or after activation.

   

  Columnar activated carbon is a kind of very fine carbon particles with strong adsorption capacity. When harmful gases (impurities) come into contact with the columnar activated carbon, they will be adsorbed, thereby achieving a purification effect.

   

  The adsorption characteristics of columnar activated carbon are divided into two types: physical adsorption and chemical adsorption.

   

  1. The chemical adsorption of columnar activated carbon: The columnar activated carbon contains carbon and other components. The small amount of oxygen on the surface during the manufacturing process can generate some functional groups. These components exist in various compound forms (such as carboxyl, hydroxyl, carbonyl, etc.), so Columnar activated carbon can be chemically adsorbed.www.activated-carbon-pellets.com

   

  1. The physical adsorption of columnar activated carbon is the adsorption produced by molecular force. Its characteristic is that the adsorbed molecules are not attached to fixed points on the surface of the adsorbent, but can move freely on the interface.
