An improved method of analysis of uranium in sea water using chelating resin

A more rapid and precise method than hitherto of determining uranium in sea water is described. The separation of uranium is done by adsorption on chelating resin in weak acid media with equilibrium batch method instead of chromatographic method as previously used. The determination of uranium is done by alpha-spectrometric method using 232U tracer and spectrophotometric method using uranyl-Arsenazo complex. The average recovery by this improved method is 100% and the standard deviation of the analytical result is below 2%. (author)
