摘要

Abstract

In this way

after experimentalmeasurement of interfacial tension

different models includingmono-exponential decay

dynamic adsorptionmodels and empirical equation are used to correlate this time-dependent behavior of interfacial tension (IFT). During the modeling approach

the induction

adsorption

equilibrium

and mesoequilibrium times as well as diffusivity of surface active components known as natural surfactant including asphaltene and resin from crude oil to the interface are obtained. In addition

the surface excess concentration of surface active components at the interface and Gibbs adsorption isothermare utilized to analyze the measured dynamic IFTs. Finally

the mechanisms of crude oil/aqueous solution IFT including (a) the activity of surfaceactive components and (b) surface excess concentration of them at fluid/fluid interface are proposed and discussed in details.
