Ding Xinda activated carbon refining processing

In general, all compounds with conjugate double bond structure, activated carbon is easy to adsorption, the more often double bond, activated carbon on its adsorption capacity is greater.

This is mainly because activated carbon has a hexagonal structure formed by the combination of covalent bonds (with large bond structure properties of aromatic ring), which is easy to be mutual www.chinactivecarbon.com/  

Some pigments, most of which have a strategic structure, are easy to be adsorbed on the carbon. In the process of recrystallization, activated carbon decolorization is added to remove impurities. This is the reason.

For the same skeleton compounds or the same type of compounds, the introduction of amine, hydroxyl, carboxyl and other polar groups will often increase the adsorption of activated carbon to it.

The adsorption power of activated carbon on the material is related to the structure of the adsorbed material and the solvent used.wholesale activated carbon pellet 

The adsorption capacity is usually strongest in water, followed by ethanol and acetone, and weaker in other solvents.

Therefore, the decolorization with activated carbon is the best in aqueous solution, followed by ethanol and acetone, and almost no decolorization ability in other organic solvents.

The size of the adsorption force of activated carbon on the solute in the solution, in addition to the size of the activated carbon and the structure of the adsorbed matter, must also consider the interaction between solute and solvent, that is, must also consider the size of the solute solubility of the solvent.

Activated carbon chromatography is often carried out in an aqueous solution, the solubility of the adsorbate in water when there is a key role in the adsorption capacity or adsorption stability.

For example, the adsorption of activated carbon on iodine, flash iodine in the water towel solubility is minimum, so the adsorption of activated carbon in water is the largest.

Another example of activated carbon on the adsorption of trans butadienoic acid is greater than cis butadienoic acid, the reason is that the solubility of trans butadienoic acid in water than cis butadienoic acid.
