A STUDY INTO THE FORMATION PROCESSES OF URANIUM NANAOCLUSTERS WITH VARIABLE VALENCE WHILE URANYL SOLUTIONS WITH DIMETHYL FORMAMIDE ARE SUBJECTED TO IRRADIATION AND DEPOSITED ON GLASS SURFACE

Abstract

Using the methods of electronic and IR absorption, we have studied the photochemical formation processes of the complexes between tri-, tetra-, and pentavalent uranium and organic ligands when the solutions of UO2(NO3)3*6H2O in dimethyl formamide, UO2(NO3)3*6H2O in dimethyl formamide with the addition of CCl4, and UO2(ClO4)3*5H2O in dimethyl formamide were subjected to the effect of light-diode radiation (430-450 nm). The possibility for deposition of the complexes of tetra- and pentavalent uranium on the glass surface was established.
