Liquid-Liquid Extraction: Kinetics and Thermodynamics

A general approach to liquid-liquid extraction will be developed through the concepts of thermodynamics and kinetics, with the aim of understanding the mechanisms responsible for extraction as well as the processes occurring at the liquid-liquid interface. The fundamental aspects of other types of extraction (liquid-solid, supercritical fluid extraction, and distillation) will also be covered.

The objective of this course is to provide an overview of the fundamental principles of the kinetics and thermodynamics of liquid-liquid extraction. It will also introduce the main concepts and processes involved in extraction (liquid-liquid, liquid-solid, or critical fluid extraction) and distillation.
