    The determination of U, Np and Pu in urine by sequential extraction with alamine-336 from hydrochloric acid medium
    (T.A.E.C., Çekmece Nuclear Research And Training Center, 1974) Veselsky, J. C.; Kırl, Pak Chan; Sezginer, N.; TAEK-ÇNAEM
    A method has been developed for the extraction of uranium, neptunium and plutonium from human urine using the comparatively cheap technical amine ALAMINE-336. These elements are coprecipitated with a calcium phosphate carrier, which is then subjected to a wet-ashing procedure with HN0(3)/H(2)0(2) HCl/H(2)O(2). The residue is dissolved in 10M hydrochloric acid and U, Np and Pu are extracted with a 10% ALAMINE-336/xylene solution, followed by subsequent back-extraction with 10M HCl/NH(4)I (Pu), 4M HC1/HF (Np) and 0,1M HCİ (U), respectively. The average recoveries are around 95%.
