ABSTRACT

Adsorption of a substance involves its accumulation at the interface between two phases. The molecule that adsorbs at the interface is called an adsorbate, and the solid on which adsorption occurs is the adsorbent [1]. Adsorbents of interest in water treatment include activated carbon; ionexchange resins; adsorbent resins; metal oxides, hydroxides, and carbonates; activated alumina; clays; and other solids that are suspended in or in contact with water [1].
