“…[30][31][32][33] This is a background for tailoring the Ln,Zr,Mo-based ceramics as a waste form for HLW lanthanides and/or actinides (Ln-An) and, for example, sediment-forming by-products of the SNF processing, such as Mo and Zr being subject to removal from the PUREX streams and immobilization. 26,29 The stability of the new host phases as the most important property for such kinds of materials is not evident now but predictions based on the bonding type 19 classify Zr-bearing metal oxides as resistant to amorphization.…”

“…Studies on the separation of Mo from high-level liquid waste have been carried out using various techniques, such as solvent extraction [4][5][6], resin adsorption [7,8], and precipitation [9,10]. Among these methods, solvent extraction is an effective method for dealing with a large amount of liquid waste.…”

Comparative investigations were carried out to study the influence of TBP on Mo extraction by HDBP solutions in xylene and TBP in xylene. The dependences of D Mo on HNO 3 concentration for both HDBP and D2EHPA have minima at about 3 mol/L HNO 3 . This shows similar extraction properties of HDBP and D2EHPA. The presence of TBP in the solvent results in the reduction of Mo extraction and in an increase in the formal slopes of the falling and rising parts of the logD Mo -log[HNO 3 ] curve from -0.5 and +2 up to -2 and +4.Solvent loading curves with Mo show that in the absence of TBP a molybdenum solvate with two molecules of HDBP is formed at low acidity. Anomalous increase in the maximum solvent loading in the presence of TBP is caused by the ability of TBP to extract Mo from oversaturated low acidity solutions following the acidic mechanism. A molybdenum solvate with two HDBP molecules and one HNO 3 molecule is possibly formed at high acidity.A flowsheet for Mo recovery from HLW with HDBP-TBP solvent was tested in centrifugal contactors.
