Liquid-liquid extraction is a process that separates substances based on their chemical properties. The principle consists of bringing the contaminated feed flow into contact with a second fluid, i.e. the extraction fluid. The extraction fluid is chosen in such a way that it does not mix with the supply flow and that it dissolves the pollutant well. During the extraction process, the contamination of the supply flow will (partially) transfer to the extraction fluid, until a balance in concentration has been reached. This balance depends on the affinity the pollutant has for the extraction fluid. If several substances are present, the balance will be substance-dependent. In an additional step, the pollutant is separated from the extraction fluid so it can be reused. | Liquid-liquid extraction is a process that separates substances based on their chemical properties.
