“…In this context, the authors developed a simple rapid simultaneous separation and pre-concentration method for the determination of traces of uranium in high TDS natural waters, sea, and brine water. Uranium is commonly separated and pre-concentrated by precipitation methods [9][10][11], ion exchange and chromatographic meth¬ods [12][13][14][15], extraction methods [16][17][18][19], and sorption methods [20][21][22]. Each of these methods has merits and limitations in their application.…”

Investigations were carried out for separation/pre concentration of uranium from aqueous solutions of different TDS using Powdered Activated Carbon (PAC). Parameters like amount of PAC, contact time, pH, volume of solutions and reagents for desorption were optimized. The sorption of uranium is more than 95% at pH 4-5 using 0.5 gram PAC with a contact time of 10 minutes. The sorbed uranium on PAC is recovered using 0.8N HNO<sub>3</sub> and determined by LED Fluorimetry. Method was successfully applied to ground water, sea water and brine water. Methodology is simple, selective, cost effective with minimal skills. RSD of the method varies ± 6-14 %.
