Abstract:Uranium in aqueous solution can be extracted by sym-dibenzo-16-crown-5-oxy-acetic acid and its modified analogue 2-/sym-dibenzo-16-crown-5-oxy/-hexanoic acid into chloroform in the pH range 5.5–6.0. The extraction method combined with neutron activation analysis provides a sensitive method for the determination of uranium in natural waters.
