Simple and Rapid Spectrophotometric Method for Determination of Uranium (VI) in Low Grade Uranium Ores Using Arsenazo (III)
A simple and highly selective non-extractive spectrophotometric method is presented for the rapid determination of uranium in low grade uranium ores using arsenazo (III). The method is based on the complex formation of uranium (VI) with Arsenazo (III) at pH 2.0 ± 0.1 which showed maximum absorption at 651 nm. Uranium concentration of 10 µg g-1 with a molar absorptivity of 4.45104 mol-1cm-1 at 296 ± 2 K obeyed Beer’s law.
