Abstract:

This paper introduces the data fitting method for determination of the surface tension of n-butanol solution, and a software program was developed with MATLAB for the model fitting. With this software it is convenient to obtain the equation describing the relationship between the surface tension (σ) and the concentration (c) of n-butanol based on the Szyszkowski model. The surface excess (Γ) can be calculated subsequently, and the saturation surface excess (Γ) and cross section area of n-butanol solution can be obtained by extrapolation.
