Extraction technique based on chemical complexation and its applications

The separation technique of solvent extraction based on reversible chemical complexation features high capacity and high selectivity for separating polar organic solutes from dilute solution. The current situations of the complexastion extraction technique and its application forecast focusing on the aspects of organic carboxylic acid,phenols,organic sulfonic acids, amines and amphorteric groups containing dilute organic solutions are introduced in this article. The characteristics of complexation process and its recent advances are reviewed in this paper also.
