Abstract
When countercurrent chromatography (CCC) is used for the separation of inor ganic solutes, the retention volume may be different with the predicted one , and the separation efficiency is lower than that for organic separation. These discrepancies are illustrated by expressions of the retention volume and the height of theoretical plate from a mass transfer model, which is es tablished in the present research. The theoretical results show that the existence of chemical reactions plays a great role in the retention and the separation efficiency of CCC; a fast extraction reaction is preferable in the separation of inorganic solutes, and promoting the reaction rate can also improve the separation efficiency. CCC might be explored as a technique to measure kinetic data of extraction reactions.
