An ion-exchange procedure for simultaneous determination of 234 U, 235 U, 236 U, 238 U, 238 Pu, 239 + 240 Pu, 241 Am, and 244 Cm in groundwater and liquid radioactive wastes is described. The concentration and separation of U and Pu are performed on AV-17 anion exchanger in the chloride form from 9 M HCl. Am and Cm are separated from rare-earth elements by step-by-step elution from KU-2 cation-exchange resin in the NH + 4 form with a-hydroxyisobutyric acid (pH 4.75). Finally, U, Pu, Am, and Cm are determined a-spectrometrically.
