【Abstract】 The surface tension at the aqueous solution /air interface for binary systems of N octyl pyrrolidone (C 8P) —sodium dodecyl sulfate (SDS) and N octyl pyrrolidone (C 8P)—cetyl trimethyl ammonium bromide (C 16 TAB) was measured at 30 ℃. Surface tension-concentration curves for individual purified surfactants and their binary mixtures at a fixed molar ratio are used to calculate the molecular interaction parameters β σ and β M. The values of β σ and β M in the two mixtures are -2.70,-2.78;-1.27,-0.87,respectively.The experimental results show synergism in surface tension reduction efficiency for these two systems.更多还原
