METHOD FOR DETERMINING CONCENTRATION OF HYDROGEN PEROXIDE IN SOLUTION Russian patent published in 2019 - IPC G01N27/28 

FIELD: chemistry; physics.

SUBSTANCE: invention relates to the field of electroanalysis and electrochemical sensors and can be used in the implementation of methods of laboratory analysis or medical diagnostics. Method of determining the concentration of hydrogen peroxide in solution using a device containing a Berlin Azure-modified measuring electrode and silver chloride reference electrode, interconnected via an ammeter, involves immersing the electrodes of the device in the analyzed solution, followed by recording by the ammeter of the electric current in the circuit. Current magnitude makes a conclusion about the concentration of hydrogen peroxide in the analyzed solution in accordance with the previously constructed calibration dependence.

EFFECT: achieved technical result with the use of the invention is to simplify the signal detection system of (bio)sensors without reducing their sensitivity coefficient, as well as to increase the signal-to-noise ratio.
