| Abstract: | Free acid and uranium in uranyl nitrate solutions have been determined potentiometrically using Na2SO4–NaOH, Na2SO4–Na2CO3 and (NH4)2SO4–NaOH complexant-titrant combinations. The overall recovery of nitric acid varies in the range of 95.25 to 118.5%, depending upon the acid as well as the total uranium present, while that of uranium always a positive bias ranging from 100.2 to 106.4%. The results have been discussed in light of recent available data. It has been concluded that all the complexant-titrant combinations studied provide similar results. |
