Ah&met-A dispersion model with mass transfer was solved to obtain the frequency response for a countercurrent liquid extraction column. A least-squares method in the frequency domain was used to test the model against data taken on a laboratory column. The model was found to describe the column's aqueous phase dynamic response extremely well, and to describe the organic phase response qualitatively. Use of the model is suggested for obtaining better estimates of mass transfer coefficient and active holdups than are obtainable by other methods.

A model based on the residence time of solvent in the extraction system may be used to describe the dynamic operation of a continuous liquid-liquid extractor. It is proposed that optimum performance occurs when the extract exiting from the contactor is near equilibrium with the solution being extrac
