Description

  • Content Description: Americium is precipitated with bismuth phosphate from a nitric acid- digested urine sample. The bismuth phosphate is wet-ashed, dissolved in 6N--HCl, and the americium is precipitated with lamthanum fluoride. The lanthanum fluoride is metathesized to the hydroxide, and the precipitate is dissolved in 2N- nitric acid. Removal of concurrently metabolized plutonium is accomplished by liquid-liquid extraction of the nitric acid soiution with 0.1-M di(2- ethylhexyl)phosphoric acid (D2EIIPA) in chloroform. The purified americium is carried on lanthanum fluoride. The precipitate is slurried onto a stainless steel plamchet and counted in a low-background proportional alpha counter. The method is effective for quantitative separation from plutonium and uranium. Quantities of the order of 0.5 dpm of americium cam be detected in a urine sample. (auth)
