A procedure is described for the determination of the uranium content of sea water. The uranium is first separated and concentrated from 4 liters of sea water by solvent extraction with di-(2-ethyinexyl)-phosphoric acid in carbon tetrachloride. A further purification of the uranium is carried out by the extraction of uranyl nitrate into ethyl acetate, and the uranium concentration is found by pulse polarography using the peak from a perchloric acid-tartrate supporting electrolyte. U-237 is employed as a radioactive tracer to measure the percentage recovery of uranium in the chemical separation processes. The value obtained for English Channel water is 3.3 plus or minus 0.08 mu g of u/l. (auth)
