A titrimetric method for the sequential determination of thorium and plutonium

A method for the sequential determination of Th and Pu in thorium nitride and PuO sub 2 has been developed. In the sample solution containing Th and Pu, Th is first determined by complexometric titration with EDTA and then in the same solution Pu is determined by redox titration employing potentiome...

Summary:A method for the sequential determination of Th and Pu in thorium nitride and PuO sub 2 has been developed. In the sample solution containing Th and Pu, Th is first determined by complexometric titration with EDTA and then in the same solution Pu is determined by redox titration employing potentiometry. Prior to the determination of Pu, EDTA is destroyed by fuming with concentrated HClO sub 4 . Thorium is determined at 10 mg level and Pu at 1 mg level with precision and accuracy of > plus/minus 0.5%.--AA
