Solvent extraction and ion exchange studies on the separation of Ce, Nd, Gd, Tm and Zr

الملخص EN

The sorption behavior of ionic species of Ce, Nd, Gd, Tm and Zr elements has been studied from carbonate solutions on organic and some prepared inorganic ion exchangers.

In addition, their extraction behavior, in the presence of each other, from aqueous solutions containing ethylendiaminetetraacetic acid (EDTA) and diethylenetriaminebenta acetic acid (DTPA) with the organic extractants: bis- 2(ethylhexyl)phosphoric acid (HDEHP), tributyl phosphate (TBP), N-lauryltrialkeyl amine (Amberlite-LA-2) and tricaprylmethyl ammonium chloride (TCMA) in toluene, has also been studied.

The influence of some factors affecting the extraction and the sorption of ionic species of the aforementioned elements has been studied.

Good separation of the studied elements from each other has been achieved.
