Adsorption properties of the stearic acid-octadecane particles in aqueous solutions

The adsorption properties and surface charge creation for the stearic acid and octadecane/aqueous electrolyte solutions are considered. The hairy stru cture of surface charge for these systems was confirmed on the basis of pot entiometric titration, ion adsorption and electrophoretic measurement data. For. the system with stearic acid the reaction of ionization and complexat ion of carboxyl groups of stearic acid molecules from subsurface layer are responsible for the creation of surface charge and adsorption properties. T he surface charge at octadecane particle is probably the results in adsorpt ion and orientation of water molecules at the interface.
