Abstract

The paper discusses a method developed for the determination of uranium in uranyl nitrate raffinate (UNR) generated through sodium di-uranate (SDU) process using inductively coupled plasma atomic emission spectrometer (ICP-AES). High concentration of Na in UNR limits the direct determination of uranium in ICP-AES. Therefore, selective extraction of uranium from UNR using tri-n-octyl-phosphine oxide (TOPO) and stripping by ammonium carbonate was followed. Effect of sodium on estimation of uranium is discussed. The method has been validated by standard recovery of spiked real time UNR samples with known amounts of uranium CRM (Merck-HC42984673). The developed method compared well with EDXRFS and Redox titrimetric methods.
