AMPEROMETRIC DETERMINATION OF NITRITE IN BIOLOGICAL MEDIA
The article is devoted to the study of the possibilities of determining nitrite in biological media by the amperometric method using a composite electrode based on multi-walled carbon nanotubes and poly (methylene blue). It has been shown that in healthy persons and patients with an inflammatory reaction, the values of currents of nitrite oxidation in the blood serum differ significantly. An inverse correlation was found between the obtained values and the values of the content of nitric oxide metabolites measured by the spectrophotometric method.
