Decolorization principle of high-efficiency decolorization powder activated carbon

High-efficiency decolorization powder activated carbon is processed by the zinc chloride method. The raw material used is high-quality wood chips, with large adsorption capacity and good decolorization performance. It is a safe and non-toxic decolorization material that can treat amino acid industry, food industry, Decolorization, impurity removal and purification in the monosodium glutamate industry, sugar industry, wine industry, etc.

Powdered activated carbon has the ability to adsorb impurities. It is precisely because of the excellent adsorption performance of powdered activated carbon that it can turn colored liquids into light or colorless. carbon pellets The adsorption principle of powdered activated carbon is to adsorb the pigment molecules in the liquid into the inside of the activated carbon. After the activated carbon is filtered out, the remaining liquid becomes transparent.

Powdered activated carbon is a non-polar adsorption material, but when the adsorbed solvent is a polar liquid, such as water and alcohol, the decolorizing ability of activated carbon is very good. The decolorizing ability of activated carbon is also related to the pH value of the solution, which is suitable for acidic solutions. For decolorization, activated carbon has a weak adsorption effect on polar solvents, and the polarity of impurities and pigments is less than that of water, so powder activated carbon has strong adsorption of impurities and pigments, so as to achieve the effect of decolorization.

When using powdered carbon, an adsorption test must be carried out according to the type and concentration of pollutants to be removed to determine the type and quantity of activated carbon. coconut shell granular activated carbon Before adding powdered carbon, attention should be paid to first making carbon powder into carbon slurry and adding it quantitatively and evenly. In water, the longer the contact time, the better the decontamination effect. When in use, the powdered activated carbon is more labor intensive during loading, unloading, unpacking, etc., which can easily cause dust to fly, so handle it with care and keep it as low as possible. operating.
