METHOD TO DETECT RHENIUM BY KINETIC INVERSION-VOLTAMMETRIC METHOD IN ROCKS AND ORES Russian patent published in 2014 - IPC G01N27/48 

FIELD: measurement equipment.

SUBSTANCE: invention is aimed at detection of rhenium in rocks and ores by kinetic inversion-voltammetric method and may be used in different industries to detect content of concentrations of various metal ions in solutions. The method according to the invention includes detection of rhenium on the background of 0.1 M H₂SO₄ with addition of 0.03 ml of 30% H₂O₂ by the method of kinetic inversion voltamperometry, when electric concentration of rhenium is carried out in a mercury film electrode with subsequent registration of cathode peaks, taking voltamperegrams at the speed of potential deployment of 100 mV/s, at the same time the concentration is determined by the height of the cathode peak in the range of potentials from 0.0 to 0.20 V by the method of addition of certified mixtures.

EFFECT: invention makes it possible to exclude using highly toxic materials when detecting ions of rhenium (VII), and also provides for higher accuracy, resolution and express nature of determination.
