Microviscosity of ions and salting-out in solvent extraction of rare earths and transplutonium elements by various extractants

Creators

Description

The use of microviscosity (the viscosity of the first hydration shell of ions) for the description of salting-out effect in extraction systems has been investigated. The dependences of solvent extraction of rare earths and transplutonium elements with trioctylphosphine oxide and aliquat 336 on the microviscosity of various ions as salting-out agents have been determined. The results indicate that it is possible to use the microviscosity for the explanation of saltin-out action of cations
