Crowther, A B

A rapid method for the determination of lead in uranium was developed provided the metal is not grossly contaminated with metals which react with dithizone. The lead is separated by extraction with dithizone in chloroform in presence of citrate, hydroxylamine hydrochloride, and potassiunn cyanide from a solution of the metal made alkaline with amnnonia to litmus. The extract is washed with cyanide-amnnonia solution and, if thallium is present, with dilute cyanide. The lead dithizonate can then be estimated colorimetrically. (auth)
