Beard, H C

A better quantitative analytical method was sought for the separation and identification of the cations of arsenic, antimony, and bismuth. This was accomplished by using the methods of complexation, solvation, and precipitation. All cations in HCl solution were reduced, the solution made 10N in HCl, and the arsenic extracted with benzene. The benzene layer, made 6N in HCl reduced the cation to metallic arsenic with sodium hypophosphite. The aqueous layer was oxidized and the antimony extracted with isopropyl ether. It was recovered from the ether layer by reduction which transferred it to the aqueous layer. The antimony was further reduced in HCl sofution by chromous chlonide to the metal. The aqueous layer from the isopropyl ether was made acid with HCl and the bismuth reduced with chromous chloride to the metal. It could also be determined as the quinolate. Distillation and sulfide precipitation were eliminated in this procedure and all cations were precipitated as the metals. Using As/sup 76/, Sb/ sup 122/, and Bi/sup / 2>s/sup 10/ the efficiency of the separations was determined. The separations was determined. The separated metals were identified by beta absorption measurements and half life determinations. Reproducibility was excellent and in both chemical and radiochemical determinations the deviations were not more than 2.0%. This is a clean, accurate, reproducible, and rapid method for the analytical radiochemical separation of arsenic, antimony, and bismuth. A comprehensive bibliography is appended. (auth)
