dc.description.abstractPreconcentration of uranium from natural water samples using Chelex-100 cation-exchange resin, its selective extraction by tributylphosphate and electrodeposition on stainless steel discs is reported. The validity of the separation procedure and the chemical recoveries were checked by addition of uranium standard solution as well as by tracing with 232U. The average uranium yield for the cation-exchange was (97±2)%, for the liquid-liquid extraction was (95±2)% and for the electrodeposition was more than 99%. Employing high-resolution α-spectroscopy, the measured activity of 238U and 234U radioisotopes was found to be ∼7 mBq·l-1 and ∼35 mBq·l-1 for ground- and seawater samples, respectively. The energy resolution (FWHM) of the α-peaks was 22 keV, the minimum detectable activity (MDA) was estimated to be 1 mBq·l-1 (at 95% confidence limit).en
