ADSORPTION MODIFYING IONOGENIC SURFACTANT ON ALUMINA WITH DIFFERENT ACID-BASE CHARACTERISTICS

Abstract

Studied the adsorption of ionic surfactants on the surfaces of alumina with different acid-base functions. It is shown that the most effective modification of the surface of alumina of various types can be accomplished with the use of anionic surfactants. And the formation of primary monolayer with a vertical orientation of the molecules, ranging from low concentrations, in the case of surfactants with higher molecular weight and the number of hydrocarbon radicals.
