ABSTRACT

Adsorption at the solid–liquid interface has been an area of great interest to the researchers. This interest basically stems from the role adsorption plays in influencing and affecting a large number of processes commonly used in laboratory and industrial practice. The important applications where solid–liquid interface plays a major role include froth flotation of minerals, flocculation and selective flocculation, dispersion, sedimentation, processing of fertilizers, and production of paints. A large number of investigations have been carried out on the adsorption of surfactants on the surfaces of inorganic substances such as ores, minerals, inorganic oxides, metals, and fertilizers.
