Description
| - There is an intensive research effort directed to finding suitable oxide ceramics for use as radioactive waste storage forms [1,2] and to finding new innovative methods of their preparation. A good example of these methods is rapidly developing application of sonochemistry. In this work we used non-radioactive nuclides as models for highly radioactive elements. For example, based on the charge analogy and similarities in ionic radii, we used La3+ for Am3+, Ce4+ for Pu4+ and UO22+ for PuO22+. We studied sonochemically driven synthesis of insoluble lanthanide and uranium containing precipitates from the selected metal precursors, such as metal acetylacetonates, in organic solvent – tetraglyme (tetraethylenglycol dimethylether, TGL). Sonolysis of a series of metal acetylacetonato complexes, M(acac)3, M = La, Ce, Pr, Nd, Eu, Gd, Dy, Er, and UO2(acac)2 was carried out in TGL under Ar atmosphere on a Sonics and Materials VXC system with 500 W input power and working frequency of 20 kHz.
