Abstract

With quasi-lattice model, surface tension equations for binary solution are derived assuming both mono-and multi-layer surface models. These equations are in agreement with Gibbs adsorption isotherm, and therefore surface relative adsorption can be calculated. The chemical potentials of bulk phase components obtained are also indifferent even if the influence of surface phase is taken into account.

이성분용액의 표면을 단분자층 또는 다분자층으로 가정할 때의 표면장력식을 통계열역학적으로 유도하였다. 이 표면장력식들은 Gibbs흡착식을 만족시켜 주며, 따라서 표면에서의 흡착을 계산할 수 있다. 또한 이때 얻은 bulk용액의 화학포텐샬이 열역학적으로 유도된 것과 같다는 것을 보였다.
