Abstract

 

Determination of depleted uranium (DU) in the presence of natural uranium (NU) by inductively coupled plasma mass spectrometry (ICP-MS) was applied on environmental soil samples collected from Doha city, Qatar. The soils were artificially spiked by soaking them in a mixture of DU and NU. It was observed from sequential experiment that uranium was brought into solution and mainly appeared at steps for dilute acid-soluble, carbonate-bound and organic matter-bound species. Little redistribution was observed at steps for exchangeable and Fe-Mn oxide-bound species. The detection limit of 235U and 238U isotopes, trueness, precision, specificity, and stability were determined. The recoveries of the uranium through whole extraction procedure were in the range of 87 - 96%.

Key words: Depleted uranium, ICP-MS, removal, sequential extraction.
