A portable fluorescence analyzer for determining uranium(VI) in natural waters

摘要

A portable fluorescence analyzer has been developed for determining 0.03-3000 ng/L of uranium(VI) in various types of waters; the relative standard deviation is 10%. The principle of time selection of the luminescence of analyte and the impurities has been used. In contrast to the previous apparatus with a bulky nitrogen laser or a low-power light diode, this apparatus involves a powerful pulse xenon lamp.
