Dynamic interracial characters are investigated for solvent extraction system of metals by organophosphoric or phosphonicacid.The relationship between interfacial characters and kinetic parameters shows that the dynamic interfacial properties are im-portant to mass transfer processes in liquid-liquid extraction.The authors develop a two-film adsorption model,which may offera basis for researching interfacial activity in mass transfer process.
