Voltammetric determination of tannic acid in beverages using pencil graphite electrode [PDF]
Czech Journal of Food Sciences, 2015 The pretreated pencil graphite electrode (Pre-PGE) prepared by a chronoamperometry technique was applied for the determination of tannic acid using anodic stripping differential pulse voltammetry. The currents obtained from voltammetry measurements at optimum conditions were linearly correlated with the concentration of tannic acid.
