摘要：
The thermodynamics of adsorption of large surface active compounds at the interface between two immiscible liquids is considered. These molecules are supposed to substitute at the interface a number of adsorbed molecules of both solvents. Gibbs free energy and the isotherm of adsorption of surface active amphiphilic compounds were calculated. The adsorption isotherms of dry and wet chlorophyll a at the octane/water and air/water interfaces are measured. The difference between the adsorption behavior of chlorophyll a dissolved in dry and wet octane is discovered. The thermodynamic parameters of chlorophyll monomer and hydrated oligomer of chlorophyll a adsorption at octane/water interface are determined. © 1992.
