| 520 | |a"A procedure is described for the determination of total rare earth oxides in high grade uranium products, based on the use of solvent extraction with long-chain alkyl amines. Extraction with tri-isooctylamine from strong hydrochloric acid medium removes uranium, zirconium, and a number of other ions. This is followed by a second extraction from sulphate solution, employing di(tridecyl P) amine to remove thorium. Folrowing further conventional purification steps, mixed rare earth oxides are determined by ignition to the oxides, or by a suitable colorimetric method"--Synopsis, page i. |
