Abstract: The separation technique of extraction based on reversible chemical complexation is of high efficiency and high selectivity for separating polar organic solutes in the dilute solution. The current applications of the extraction based on the reversible chemical complexation technique for the extraction of Lewis acid, Lewis alkali, the dilute solution of amphoteric organics, extraction kinetics and salt–out effect on extraction equilibrium from 2004 years are presented. The development and application of the extraction based on reversible chemical complexation are forecasted.
