Fluorinated Carbonates as New Diluents for Extraction and Separation of f-Block Elements

The fluorinated carbonate BK-1 solvent was studied as a diluent in extraction systems with different extracting agents - CMPO, THDGA, CyMe 4 -BTBP, and CyMe 4 -BTPhen, which are the most promising molecules for separation of minor actinides and lanthanides. Dependence of the extraction properties of...

Description
Summary:The fluorinated carbonate BK-1 solvent was studied as a diluent in extraction systems with different extracting agents - CMPO, THDGA, CyMe 4 -BTBP, and CyMe 4 -BTPhen, which are the most promising molecules for separation of minor actinides and lanthanides. Dependence of the extraction properties of the system on the concentrations of HNO 3 or extracting compound, kinetics of trivalent metal extraction and extraction of the ions by neat diluent (without the addition of extracting agent) were investigated. Based on the obtained results, BK-1 is a promising candidate diluent for f-block metal separation.
