Zilberman, Yu. Fedorov] Infrared absorption spectra of HNO3 solutions in UO2(NO3)2(TBP)2 have been taken. The formation of a hydrogen bond between HNO3 and nitrate or phosphoryl group in UO2(NO3)2(TBP)2 has been established. On extracting Pu(IV) and Np(IV) by 30% TBP-dodecane, dependence of the distribution coefficients on concentration has been found at UO2(NO3)2 concentrations in the aqueous phase upwards from 0.4M. This dependence appeared in the temperature interval 0-60°C. Such effects may be caused by ordered structure of saturated uranyl nitrate solutions in TBP. Akadémiai Kiadó, 1990 Zilberman B.
