AbstractAbstract
[en] A highly sensitive rapid method for determination of rhenium in sulfuric acid solution containing Re(7) is proposed. The method includes hydrocloric acid introduction into initial solution (2-10 vol. %), Re(7) reduction to Re(6) by ultraviolet irradiation (230-300 nm) and subsequent Re(6) detection by spectrophotometric or electron paramagnetic resonance method. The rhenium detection limit is 1 μg/ml, error of determination is ±2%
