Abstract

A new and simple method for separation and determination of U and Th in manganese nodules has been developed.The results show that the addition of NH₄NO₃ to the dilute HNO₃ medium increases the selectivity of anion-exchange separation of U and Th.The simple procedure and high recoveries of the method make it valuable to the analyses of U and Th in manganese nodules.
