Batch extraction of amines using emulsion liquid membranes: Importance of reaction reversibility

Abstract

Abstract Experimental results for the batch extraction of amines using emulsion liquid membranes with an internal aqueous HCI solution are presented. Four amines and mixtures of one binary pair were studied. Reversibility of the acid‐amine reaction within the internal droplets affected extraction rates. The reversible reaction model presented earlier satisfactorily predicts these experimental results.
