The Description of a Multi-stage Extradition Process
Abstract
Extraction is the process of the physicochemical distribution of a substance between two immiscible liquids, as well as a method for separating, isolating, and concentrating substances. During extraction, the following processes occur: the formation of extractable compounds, the distribution of extractable compounds between the aqueous and organic phases, and reactions occurring in the organic phase-dissociation, association, and polymerization. For the transfer of metal ions and other charged particles into the organic phase, it is necessary to neutralize their charge. In the extraction of ion-associates, the charge and size of the ions are significant: as the charge increases and the size decreases, the extraction efficiency deteriorates. Under equal conditions, monovalent ions are extracted less effectively. Under equal conditions, more stable complexes are extracted more efficiently.
