2.2 Solvent Extraction and Separation of 233 U from Thorium. Here again, TBP is the most widely used extractant, and depending on whether only 233 U or both thorium and 233 U are to be recovered, the TBP content in the diluent (usually Shell Sol-T, dodecane or n -paraffin) varies. Generally, 3–7.5% TBP is used when 233 U alone is to be recovered.
