How to buy high-quality activated carbon

Activated carbon is a kind of porous carbon material that uses high-quality materials as raw materials and undergoes processing, forming, carbonization, and activation. It has a certain degree of mechanical strength, a large specific surface area and strong adsorption performance.

More than 80%-90% of activated carbon is composed of carbon elements, which is why activated carbon is a hydrophobic adsorbent. In addition to the carbon element, it also contains two types of admixtures. One is chemically combined elements, mainly oxygen and hydrogen. powdered carbon activated These elements are left in the carbon due to unsafe carbonization, or in the process of activation. The non-carbon elements are chemically combined with the surface of activated carbon. For example, when activated with water vapor, the surface of activated carbon is oxidized or oxidized by water vapor.

Another type of blend is ash, which is the inorganic part of activated carbon. Water purification activated carbon is one of the simple and fast methods to remove trace organic matter in water, and it has a very significant effect on the removal of color, smell and odor in water.

There are also tricks to find high-quality activated carbon. It is not enough if only the iodine value and methylene blue value of activated carbon are considered. These two can only be used to indicate the specific surface area of the fine pores in the activated carbon particles, but wastewater treatment In actual production, there is also the problem of adsorption rate. The adsorption rate refers to the amount of solute that can be adsorbed by a unit of repeated activated carbon per unit time.www.wyactivatedcarbon.com

If it is to adsorb impurities in the water, activated carbon will continue to adsorb solutes in the water until the adsorption equilibrium, that is, the solute concentration no longer changes. At a certain temperature, when the adsorption equilibrium is reached, the relationship between the weight of the solute absorbed by the activated carbon per unit weight and the concentration of the solute in the water is called the adsorption isotherm.
