New Solvent Extraction Techniques for Uranium Purification
It is then re-extracted as a chloride anion complex by a solvent which is selective for uranium in the reduced state. Various long-chain, secondary amines have been found to be quite selective. The uranium is stripped with water and precipitated by addition of HF. The product is filtered and dried to yield very high-purity uranium tetrafluoride.
