uranium

The results of experimental approbation of geoelectric methods of forming short-pulsed electromagnetic field (FSPEF) vertical electric-resonance sounding (VERS) and the technology of satellite data processing and interpretation for the "direct" prospecting the ore minerals and water-bearing reservoirs are analyzed.

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 4.45104 mol-1cm-1 at 296 ± 2 K obeyed Beer’s law.
