| Abstract: | with silica gel H/carboxylmethyl cellulose/ammonium nitrate as thin layer, and trioctylphosphate/tetrahydrofuran/nitric acid/ether (3: 18: 2: 18) as mobile phase, Lanthanum, Cerium, Praseodymium, Neodymium, Samarium can be separated from each other in a mixture of light rare earth elements. Besides, good results for separation of Yttrium from other light rare earth elements; Lanthanum, Cerium, Praseodymium, Holmium and Scandium from a mixture of rare earth elements can also obtained, This method is being used in the separation and measuring of rare earth elements fron monazite sand. |
