FIELD: chemistry.SUBSTANCE: invention relates to the field of electrochemical methods of analysis, in particular to the analysis of solutions to determine the total antioxidant/oxidant activity. The invention can be used in research laboratories, food industry, medicine to determine the antioxidant/oxidant activity of natural, synthetic and biological objects to study antioxidant/oxidant properties of substances and products, control the composition of food products, and diagnose diseases. The essence of the claimed method consists in the following: determination of the antioxidant/oxidant activity is carried out by a difference of potentials, one of which is measured after the realisation of a chemical reaction between antioxidants/oxidants of an analysed substance and an applied agent, and the second one - after the following addition of a solution of a reagent or the analysed substance.EFFECT: invention provides an increase of accuracy, reliability and reproducibility of results, increase of the analysis expression, extension of the range of analysed substances, applied reagents and solvents.3 cl, 6 dwg, 6 ex |
