Abstract: The interfacial activity of HDEHP at n-octane/0.05 mol/L(H2,Na2)SO4interfacewas investigated at 298 K. Different adsorption isotherms such as the Gibbs,Szyzkowski and Polynomial were found as fits well to experimental interfacial tension isotherms. The interfacial adsorption parameters,CAC, Cmin,Aiand the free energy of adsorption △Gadwere calculated,respectively.
