ABSTRACT

Adsorption from liquid phase can take place at any of the three interfaces: liquid-solid, liquid-liquid, or liquid-vapor. In practice, however, more attention has been directed and more is known about the liquid-solid interface. This is due to the fact that purification of liquids such as water, wine, and oils, and their decolorization and detoxification have been carried out for centuries using charcoals and active carbons. With the expansion of chemical, pharmaceutical and food industries the range of substances to be purified by carbons has increased enormously.
