Description

A general approach to liquid-liquid extraction will be developed through notions of thermodynamics and kinetics, with a view to understanding the mechanisms responsible for extraction as well as the processes taking place at the liquid-liquid interface. Fundamental aspects of other types of extraction (liquid-solid, supercritical fluid, distillation) will also be covered.
