Development of voltammetric methods for antioxidant activity determination based on Fe(III) reduction

Numerous methods have been developed for determination of antioxidant (AO) activity in vitro, but only several spectrophotometrical assays are frequently applied. Among them, probably the most simple is FRAP assay, based on the reduction of Fe(III) to Fe(II) by antioxidants. In this work the applicability of that reaction for the development of electrochemical method for AO activity determination was examined. The two common electrochemical...
