Redox Control in Solvent Extraction Studies Using a PEEK AKUFVE Unit

When studying actinides or other elements with different possible oxidation states it is important to control which state is present in solution. Earlier redox control has been done by adding some other element to the solution but this approach introduces additional uncertainties. Since the sixties...

Description
Summary:When studying actinides or other elements with different possible oxidation states it is important to control which state is present in solution. Earlier redox control has been done by adding some other element to the solution but this approach introduces additional uncertainties. Since the sixties the AKUFVE apparatus has been used for precise solvent extraction studies. Now this equipment has been improved with redox control facilities, additional thermal control, and all parts in contact with the liquids are made of polyetherether ketone (PEEK) to minimize sorption.
