Complexation between uranyl(Ⅵ)and CMPO in a hydroxyl-functionalized ionic liquid:An extraction,spectrophotography,and calorimetry study
文献摘要：
The extraction complexes of uranyl(Ⅵ)in HNO3 to a hydroxyl-functionalized ionic liquid(IL)phase,HOEtmimNTf2 bearing CMPO,were investigated.Three possibly successive extraction complexes,UO2L2+(L=CMPO),UO2L22+and UO2L32+,were detected based on variable U/L ratios.Uranyl(Ⅵ)prefers to be extracted as complex UO2L32+,combining with the ions from HOEtmimNTf2 to construct a solid mate-rial through self-assembly.The thermodynamics of complexes,UO2Lj2+(j=1-3),were studied by spec-trophotometry and microcalorimetry.All the formation reactions are principally driven by entropy,al-though a small part of the driving force of complexes UO2L22+and UO2L32+comes from enthalpy.Based on the thermodynamic properties for complex UO2L32+,we provide a possible coordination mode in HOEtmimNTf2:the first CMPO molecule coordinates with UO22+in a bidentate fashion while the oth-ers do in a monodentate fashion.The results offer a thermodynamic insight into the formation behaviors of the uranyl(Ⅵ)/CMPO complexes involving the special IL HOEtmimNTf2,which is of significance to ad-vance the novel IL extraction strategy.
