摘要：

A recurrent method for synthesis of diphosphine dioxides to be used for extraction of actinides from acidic aqueous solution is described. Selective phosphonium salt formation and cleavage permits the stepwise introduction of different bridges between the phosphorus atoms as well as various chains on them. The influence of the structural parameters on liquid-liquid extraction properties of plutonium, neptunium, and americium is studied. Plutonium and neptunium can be efficiently removed from radioactive contaminated liquid wastes, using the supported liquid membranes technology with the more lipophilic organophosphorus extractants.
