      Processes' occurring at the Ag/AgCl/Cl-, ([Fe(CN)6]3-/4-) ions interface study results are presented. Conditions are selected for the mixed salts' precipitate formation on the silver surface. It has been shown that the potential of a silver screen-printed electrode (AgSPE) coated with amixed precipitate containing silver chloride/ferricyanide is stable in the presence of [Fe(CN)6]3-/4-. The electrode can serve as a quasi-reference electrode (QRE) in electrochemical measurements in media containing ions [Fe(CN)6]3-/4-. The electrode is formed during polarization of AgSPE (0.325 V vs. Ag/AgCl/KCl, 3.5M) in a solution containing chloride-and ferri/ferrocyanides ions. The results of the obtained QRE study by potentiometry, scanning electronmicroscopy and cyclic voltammetry are presented. The proposed QRE was used in a sensor system to evaluate the antioxidant activity (AOA) of solutions by hybrid potentiometricmethod (HPM). The results of AOA assessment of fruit juices and biofluids obtained using new QRE and commercial Ag/AgCl RE with separated spaces do not differ. © 2020 by the authors.
