ABSTRACT
The main research field of actinides solution chemistry has been related to the development of separation and analytical methods of actinide ions. There are recent studies on a novel electrolytic separation method1) and an electrochemical ion-sensor technique,2) both of which are based on ion transfer reaction at the interface of two immiscible solution phases. Fundamental electrochemistry of the phase transfer for actinide ions, however, has not been studied extensively. In this presentation, the author will describe (i) the ion transfer reaction of actinide (An) ions such as An[sup 3+], An[sup 4+], AnO[sub 2][sup +] or AnO[sub 2][sup 2+], where An=U,Np,Pu, across the aqueous(w)/organic (org) solutions interface and (ii) the development of an electrolytic ion separation method as well as actinide-ion selective electrode (An[sup n+]-ISE) on the basis of the ion transfer reaction. © 2000 American Institute of Physics.
