ANALYTICAL METHOD FOR THE ABSORPTIOMETRIC DETERMINATION OF TRACE THORIUM IN URANIUM SOLUTIONS

Technical Report ·
OSTI ID:4025260
Thorium is separated from uranium by co-precipitation on lanthanum fluoride. Fluoride is largely removed by evaporation with nitric acid but residual traces are complexed using aluminum chloride solution. Thorium is determined absorptiometrically as the "Thorin" complex. (auth)
