Complexation of uranium(VI) with acetohydroxamic acid

Application of Nuclear Techniques to Nuclear Waste Management


The advanced separation extraction process based on tri-n-butyl phosphate organic phase called UREX is being developed to separate uranium from fission products and other actinides, and the acetohydroxamic acid (AHA) is employed to reduce and complex plutonium and neptunium in order to decrease their distribution to the TBP-organic phase. In this study, the extraction of uranium was performed from various aqueous matrices with different concentrations of HNO3, LiNO3, and AHA. Extraction of uranium increases with increasing both initial HNO3 and total nitrate concentration. UV-VIS spectrophotometry confirmed that AHA is involved in the complex of uranium with TBP.
