Liquid–liquid extraction (LLE) is a technique that consists in the transfer of the target compound(s) from their original medium to a water-immiscible solvent, namely extractant solvent, with which the sample is put in contact during a certain time (see Figure 1).The contact between the two immiscible phases is enhanced mechanically, typically by …

Distillation is an effective method to separate mixtures that are comprised of two or more pure liquids. Distillation is a purification process where the components of a liquid mixture are vaporized and then condensed and isolated. In simple distillation, a mixture is heated, and the most volatile component vaporizes at the lowest temperature. ...

The basic procedure for performing a liquid-liquid extraction is to take two immiscible phases, one of which is usually water and the other of which is usually an organic solvent. The two phases are put into a device called a separatory funnel, and compounds in the system will distribute between the two phases.
