Abstract
A study on the adsorption mechanism of the commercial active carbon in liquid phase was made, from electrochemical as well as structural stand points.
It seemed that the adsorptive power was greatly controlled by the pore size distribution.
The determining factor for the adsorptive power was the appropriate pore size for the substance to be adsorbed, and the electrochemical property on the surface was found to be rather minor factor.
Ash content and quality or certain other impurities (for example some anion etc .) in commercial active carbon showed certain effect on the adsorptive power for small ions such as inorganic monomeric ion, but little effects for substances having large radius such as organic dyestuff.
