✦ Synopsis

A new development in separation science is the application of liquid ion exchangers. For the separation of metal ions, additional complexing in the aqueous phase can be favourable in some instances. The best method for increasing the efficiency of a separation is to impregnate an inert support with the exchanger. A number of analytical problems can be solved, and reversed-phase chromatography is useful especially in the separation of rare earth elements. From the chromatographic data, conclusions on the behaviour of ion-exchange resins, extractants and reactions in the aqueous phase can be drawn.
