These readings seem old, but they are still relevant. For example, the same principles are used in modern bioseparations.

  1. A reading on solvent extraction principles
  2. A general article on liquid liquid extractors.
  3. An interesting reading on safety in liquid-liquid extraction plants: a further reason for counter-current operations to minimize solvent use.
