Popis: | Differential voltammetry as well as UV–vis spectrophotometry and impedance spectroscopy were used to show that polyaniline doped with polystyrenesulfonic acid mediates the reduction of oxygen and hydrogen peroxide in aqueous media by facilitating the formation of hydroxyl radicals and increasing the sensitivity of the electrochemical method for determining the antioxidant activity of sulfur-containing amino acids. |
