Course content

This course is an introduction to the physical chemical properties of and the laws governing liquid-liquid extractions and ion exchange processes, and how these laws are applied for separation of chemical (organic and/or inorganic, stabile or radioactive) components in a mixture. The course gives you the theoretical foundation for separating simple, uncharged molecules, simple ions, ion complexes, or large molecules with or without covalently attached metal atoms.

Learning outcome

When you have completed this course:

  • you know the principles of liquid-liquid extraction and ion exchange
  • you can define relevant concepts and parameters
  • you know which liquid properties are essential when using these methods.
  • you are familiar with formation of chemical complexes, reaction and separation kinetics, and chemical balances for liquid extraction- and ion exchange separations.
  • you have an overview of different ion exchange materials and their physical and chemical propoerties.
  • you are familiar with modern methods for liquid-liquid extraction and ion exchange


Students who are admitted to study programmes at UiO must each semester register which courses and exams they wish to sign up for in Studentweb.

If you are not already enrolled as a student at UiO, please see our information about admission requirements and procedures.


Recommended previous knowledge

To profit from this course, you need a basic understanding of chemistry. Knowledge corresponding to KJM1100 – General chemistry (continued) and KJM1120 – Inorganic Chemistry (continued) is recommended.

Explanations and appeals

Resit an examination

Students who can document a valid reason for absence from the regular examination are offered a postponed exam at the beginning of the next semester.

New examinations are offered at the beginning of the next semester for students who do not successfully complete the exam during the previous semester.

We do not offer a re-scheduled exam for students who withdraw during the exam.

Withdrawal from an examination

It is possible to take the exam up to 3 times. If you withdraw from the exam after the deadline or during the exam, this will be counted as an examination attempt.

Special examination arrangements

Application form, deadline and requirements for special examination arrangements.


The course is subject to continuous evaluation. At regular intervals we also ask students to participate in a more comprehensive evaluation.
