Description

Free acidity in uranium(VI) and plutonium(IV) solutions has been determined with sodium sulfate as complexant and sodium carbonate as titrant. The described method is simple, accurate, and applicable to all ranges of nitric acid and heavy metal concentrations relevant to Purex process. The method is adaptable for remote operation. The overall recovery of nitric acid is 99.5% with 0.7% relative standard deviation. Uranium content has also been determined in the same aliquot with a recovery of 98.5% and 1.2% relative standard deviation after the determination of acidity
