Abstract
A kinetic spectrophotometric method has been proposed for the determination of trace amount of uranium(Ⅳ) based on its catalytic effect on the phosphomolybdic acid-iodide reaction. It is selective for uranium within the range of 0-12μg/ml,and the detection limit is 0. 02μg/ml. Trace amount of uranium in thorium nitrate and scandium oxide has been determined and the results are satisfactory.
