From the chemical potential of the components in the adlayer of crystal‐impure solution interface in one layer adsorption model based on the Bragg‐William approximation with empty sites, an equation for the variation of interfacial tension connecting the amount of adsorbed solute and impurity molecules and the interaction energies between the adsorbed molecules is derived. It is shown that the amount of impurity molecules and the interaction energies play an important role in the variation of interfacial tension.
