vestigated for the separation of lead in the analysis of lead-base materials. Lead can be held on a column of used in the analysis of lead for alloying amounts (0.025 to 9%) of thorium. The thorium in the eluate is determined by titration with EDTA to the xylenol orange end determined absorptiometrically by the thoronol method. In a solvent extraction method for this separation, a 0.1 to 1 N acid solution of the sample is shaken with a solu tion of diethylammonium diethyldithiocarbamate in trichloroethylene before titration of the aqueous solumination with thoronol.
