Abstract
CUPRAC is a method used to determine antioxidants quantifying the chromophore [Cu(Nc)2]+, generated upon increases of added antioxidants to a Cu(II) containing solution. In this work, an electrochemical alternative to quantify this complex is presented using cyclic voltammetry and chronoamperometry, compared with the classical spectroscopic determinations by UV-Vis. The final results show that the analysis performed by electrochemical methodologies is statistically similar, affording an efficient determination the total antioxidant capacity.
