Columnar activated carbon used in toxic gas purification, gas
processing, industrial and domestic water purification treatment,
solvent recovery, etc, also more widely.
All aspects of the columnar activated carbon used in industrial and
agricultural production, such as petrochemical industry non-alkali
deodorization (refined mercaptan), ethylene desalted water (refined
packing), catalyst carrier (palladium, platinum, rhodium, etc.),
water purification and wastewater treatment;Power plant water
treatment and protection of the power industry,Chemical industry
chemical catalyst and carrier, gas purification, solvent recovery
and grease decolorizing, refining;Beverage, wine, MSG mother liquor
of food industry and food of refining, decolorization;Gold
extraction, the tail liquid recovery in the sector;Environmental
protection industry of the management of the sewage, waste gas and
harmful gas, gas purification;And related industries, wood floor
moistureproof, suck a cigarette filter, automotive gasoline
evaporation pollution control, preparation of various kinds of
impregnant liquid.Activated carbon in the future there will be a
very good prospects for development and broad market.
Columnar activated carbon to volatile organic compounds in water
body has better adsorption effect, can make all kinds of volatile
organic compounds in water removal rate reached 25% ~ 65%.Compare a
variety of different molecular weight organic compound adsorption
law can be seen that for volatile organic compounds, the larger the
molecular weight, the higher the removal rate of them.This is
similar to phenol adsorption law of cationic light yellow, namely
for small molecule organic matter in water, the larger the
molecular weight, the more easily by activated carbon adsorption.
Activated carbon to extractable organic matter under molecular
weight is less than 480 had a very good removal efficiency, and on
the macromolecular organic matter removal efficiency is very
low.This is mainly due to the microporous structure of the
activated carbon empty asked steric effect, too large organic
molecules to the interior of activated carbon pore, only on the
surface of activated carbon adsorption
By activated carbon adsorption effect of volatile and organic
matter compared to the following conclusion:
Activated carbon can be extracted volatile organic compounds and
organic adsorption has a larger difference.Volatile organic
compounds with the molecular weight increased, and its adsorption
effect, the better, and the decrease of the extractable organic
compounds with molecular weight, the better its adsorption
effect.This is mainly due to the volatile organic matter is mainly
some smaller polarity organic matter, and the extractable organic
matter is the polarity of organic material, activated carbon itself
can be thought of as a non-polar adsorbent, the adsorption capacity
of nonpolar substances in water is greater than the polar material
adsorption ability.And the size of the adsorbate molecule and
activated carbon show a certain proportion, the most conducive to
the adsorption.For small polar molecules, molecular weight, the
greater the more conducive to the adsorption.
