Electrochemical properties of pigment extracts from dark red corn grains was investigated by means of cyclic voltammetry (CV) and square wave voltammetry (SWV) on glassy carbon electrode (GC) in 0.1 M H2SO4. The shape of CV was typical for the oxidation of polyphenols. The antioxidant capacity of pigment from dark red corn grains was established from the charge under the anodic peaks. Quantitative determination of dark red corn pigments was performed by SWV. The linear polarization resistance (LPR) examinations were conduced in order to study the corrosion effect of polyphenolics on mild steel. Calculated corrosion inhibition efficiency ranged from 30% to 70%. Determination of the corrosion inhibition efficiency revealed that the red corn pigments have anti-corrosion effect on mild steels.
Elektrohemijska svojstva ekstrakata pigmenta iz zrna kukuruza tamnocrvene boje ispitivana su pomoću ciklične voltametruje (CV) i voltametrije pravougaonih talasa (SWV) na elektrodi od staklastog ugljenika (GC) u 0.1 M H2SO4. Dobijeni oblik CV je tipičan za oksidaciju polifenola. Antioksidativna kapacitivnost je utvrđena određivanjem naelektrisanja ispod anodnih pikova. Pigmenti iz zrna kukuruza tamnocrvene boje su kvantitativno određeni primenom SWV metode. Linearna polarizaciona otpornost (LPR) je sprovedena na niskougljeničnom (može i mekom, ali ovo je bolji izraz) čeliku kako bi se ispitalo koroziono ponašanje polifenola. Izračunata efikasnost inhibicije korozije je bila između 30 % i 70 %. Određivanje ove efikasnosti pokazalo je da pigmenti tamnocrvenog kukuruza imaju antikorozivno dejstvo na niskougljeničnom čeliku.
