Abstract
A new bifunctional extractant named phenyl-N,N-dibutylcarbamoylmethyl sulfo xide (PCMSO) is synthesized and characterized in order to investigate its s electivity and capability in the extraction from acidic nitrate media in nu clear reprocessing. The extraction of uranium(VI) with PCMSO in toluene has been studied at various concentrations of nitric acid, extractant and salt ing-out agent (LiNO3). The mechanism of extraction is discussed in the ligh t of the results obtained. The extracted species has also been investigated using FT-IR spectrometry. The related thermodynamic functions were calcula ted. The IR spectral study was also made of the extracted species.
