As a liquid-liquid partition chromatography, counter-current chromatography has advantages in large sample loading capacity without irreversible adsorption, which has been widely applied in separation and purification fields. The main factors, including partition coefficient, two-phase solvent systems, apparatus and operating parameters greatly affect the separation process of counter-current chromatography. In order to promote the applications of counter-current chromatography, it is essential to develop theoretical researches to master the principles of counter-current chromatographic separation so as to achieve predictions before laborious trials. In this paper, recent progress about separation prediction methods are reviewed from a point of the steady and unsteady state of the mass transfer process of counter-current chromatography and its mass transfer characteristics, and then it is divided into three aspects: prediction of partition coefficient, modeling the thermodynamic process of counter-current chromatography and modeling the dynamic process of counter-current chromatography.
