| Abstract: | The paper describes a method for the separation of uranium and plutonium isotopes using anion exchange resin and UTEVA™ resin in stacked sequential columns for routine analysis of river water and liquid effluent samples. The optimisation of the UTEVA™ column for separation of U is described and compared with the conventional anion exchange technique for the separation of U from Fe. The stacked anion exchange and UTEVA™ column configuration facilitates a more rapid and efficient separation of Pu and U and also reduces the quantity of reagents required for the separation. |
