Abstract
A polarographic method for the determination of micro quantities of uranium was developed. The method is based on the catalytic wave of uranyl ions which appear in the presence of nitrate ions. Several factors which affect the height and the potential of the wave were investigated. A supporting electrolyte which consists of 0.015M nitric acid, 0.015M potassium nitrate, 0.006M potassium chloride, and 0.0002% Methyl Red is most suitable for the determination of a trace amount of uranyl ion in the absence of other ions. In this solution, the catalytic wave is proportional to the concentration of uranyl ion in the range of 10/sup -8/ to 10/sup -6/M and is much larger than that in the solution proposed by Kolthoff. The reaction mechanism of the catalytic wave is also discussed. (auth)
