Diphosphine dioxides of different structure were synthesized and studied with the goal of using as a base for preparation of solid extractants. Of all the studied compounds, DPDO-11 was chosen. The solid extractant on its base was prepared by impregnation of divinylbenzene - styrol matrix with the solution of 0.8 M DPDO in fluoropol-1083. The investigation of extraction and physico-chemical properties of this solid extractant shows that it can be used for selective recovery of actinide and rare-earth elements from aqueous solutions in the wide range of acidity.
