Preliminary Separation of the Lanthanide Group Using DHDECMP

摘要

The extraction procedure of rare earth elements from complex solutions requires many separation steps, due to the high number of elements involved. Dihexyl-N,N-Diethylcarbamylmethylene phosphonate (DHDECMP) has been proved to be a very selective extractant for lanthanides and actinides. Therefore it is interesting to test such an extractant with solutions obtained by the dissolution of solid samples. The DHDECMP properties in regard to rare earths are presented and a new procedure for their separation is defined. (ERA citation 11:011604)
