A Portable Non-Destructive Tool for Uranium Determination in Aqueous Samples

The interest in nuclear safeguards is constantly growing, as more nuclear programs are being exposed all over the world. In this work, a simple, rapid and reliable method has been applied for the determination of uranium content in aqueous media based on using potentiometric sensor. The developed tool was found to be capable of verifying the operator declarations in a wide concentration range with a considerable accuracy and precision. The developed tool offers the advantage of field verification of uranyl concentration rather than taking samples for further analysis. Effect of temperature of the test solution was investigated and the isothermal temperature coefficient of the electrode was estimated. The results obtained applying this potentiometric electrode is comparable with the data obtained using UV-Visible and ICP-OE spectrometers.
