- Abstract
Extraction of U(VI), TUE, and REE from acid process solution with solutions of mono-and bidentate neutral organophosphorus compounds (NOPCs), phenyloctyl( N,N-diisobutylcarbamoylmethyl)phosphine oxide (CMPO), 2-ethylhexyl ( N,N-dibutylcarbamoylmethyl)phenylphosphinate (CMPP), and unsymmetrical phosphine oxide (UPO) was studied as influenced by γ-irradiation at different absorbed dose rates. In all cases extraction of the target radionuclides decreased with increasing absorbed dose of γ-radiation. The resistance of the NOPCs to radiolysis decreases as CMPO>CMPP>UPO owing to the difference in the structures of their molecules.
