The uranium metal sample was dissolved in hydrochloric acid and hydrogen peroxide. For the extraction of trace amounts of lead from a large amount of uranium, dithizonebenzene solution was used. To mask trace impurities of Cu, Ni, Fe, and Zn, ammonium citrate, sodium sulfite, potussium cyanide, and ammonium hydroxide were added to the sample solution. The lead extracted into the dithizonebenzene solution was shaken with and transferred into 0.45N perchloric acid, and determined by the a-c polarography. In the case of spectrophotometric determination, the absorbency of the extracted dithizone-benzene solution was measured at 520 m mu . Good agreement was obtuined between the . results from the two methods.
