Polyphosphine Polyoxides as Complexing Agents of Actinides for the Removal from the Nuclear Wastes or from the Human Body

Abstract

We synthesized two kinds of polyphosphine polyoxides. The first one has ether bridge, and the second one shows PCP linkage. Complexation properties of these compounds towards minor actinides (Np, Pu and Am) have been evaluated from liquid-liquid extraction and from transport by supported liquid membranes. In decorporation experiment, some of the synthesized phosphonates exhibit in vivo good uranyl or neptunium complexation properties.
