摘要：

A method is described which allows the determination of uranium in organic complexes following decomposition by the oxygen-flask procedure. Uranium is quantitatively determined by a direct titration with 0.01M pyridine-2,6-dicarboxylic acid, arsenazo I being used as the indicator. The end-point is sharp and the equilibrium is rapidly attained, so the titration can be carried out rapidly. The method is simple, rapid and highly reproducible. © 1979.
