“…Applying a standard procedure that is described in the literature (El Himri et al 2000), lab pretreatment for the water samples was not needed. For each sample, 20 mL of water was transferred directly to a test tube.…”

A study of the 238U content in bottled water consumed in Kuwait was performed. The bottled water samples originated from 16 different countries. Of the 41 investigated samples, 238U was detected in 23 samples in which the radionuclide's activity was determined. Consequently, it was found that activity levels of all samples were several of orders of magnitude below the guidance limits. Moreover, annual effective doses were estimated for three age groups, namely adults, children, and infants. As a result, it was found that the doses received by all age groups were several of orders of magnitude below the guideline levels. Hence, consumption of bottled water sold in Kuwait is safe for the presence of 238U.

“…The internal standards were used to correct for possible instability and drift of the ICP‐MS device during sample introduction. In spite of reagents such as rhenium, thallium, and indium can also be used as internal standard, particularly, in case of strong geological influence, use of Ir is generally accepted for the determination of different elements as well as uranium 3, 25. The stock solutions of other elements were prepared from their appropriate compounds (Th(NO 3 ) 4 · 5 H 2 O for Th, (NH 4 ) 6 Mo 7 O 24 · 4 H 2 O for Mo, NH 4 VO 3 for V, and ZrOCl 2 · 8 H 2 O for Zr, Merck).…”

“…Natural uranium consists almost entirely of the uranium‐238 isotope in its hexavalent state, which commonly associates with oxygen as the uranyl ion, ${\rm UO}_{{\rm 2}}^{{\rm 2 + }} $ . Soluble U (VI) carbonate complexes produced in soil uranium can be transferred into natural water 3. On the contrary of other toxic metals, the maximum acceptable concentration of uranium in drinking water was increased from 2.0 to 15 µg L −1 in the last 30 years by WHO and other authorities 4–6.…”

The aim of this study is to investigate the concentrations of U, Th, V, Mo, and Zr in natural waters taken from Turkey. Among these water species, Lake Van is the largest soda lake and the fourth largest closed basin on Earth Mediterranean Sea water. Mean Mo and V concentrations in the studied water samples were found to be in ranges of 0.1-17 and 2.7-113 mg L À1 , respectively. The obtained highest U concentration in Lake Van correlates with the highest Mo and Zr levels compared to the Lake Hazar and river waters. These results imply that there is a young occurrence of uranium minerals around Lake Van. It is concluded that there is about 50.000 ton of uranium in Lake Van water.

“…For the determination of trace amounts of uranium in natural samples, selective and sensitive techniques such as inductively coupled plasma atomic emission spectrometry [5], inductively coupled plasma-mass spectrometry [6], ion chromatography [7] and capillary zone electrophoresis [8] have been used. However, these techniques are high cost with restricted accessibility.…”

Spherical agarose-coated magnetic nanoparticles functionalized with a new salen for magnetic solid-phase extraction of uranyl ion

et al. 2016

The authors describe a method for magnetic solid phase extraction of uranyl ions from water samples. It is based on the use of spherical agarose-coated magnetic nanoparticles along with magnetic field agitation. The salen type Schiff base N,N'-bis(4-hydroxysalicylidene)-1,2-phenylenediamine was synthesized from resorcinol in two steps and characterized by infrared and nucleic magnetic resonance spectroscopies. The particles were then activated by an epichlorohydrin method and functionalized with the Schiff base which acts as a selective ligand for the extraction of UO 2 (II). Following preconcentration and elution with HCl, the ions were quantified by spectrophotometry using Arsenazo III as the indicator. The effects of pH value, ionic strength and amount of the adsorbent on the extraction of UO 2 (II) were optimized by a multivariate central composite design method. Six replicate analyses under optimized conditions resulted in a recovery of 96.6 % with a relative standard deviation of 3.4 % for UO 2 (II). The detection limit of the method (at a signal-tonoise ratio of 3σ) is 10 μg L‾ 1 . The method was successfully applied to the determination of UO 2 (II) in spiked water samples.Electronic supplementary material The online version of this article (
