An efficient adsorptive stripping voltammetric (AdSV) method for determination of gallic acid, GA, was developed by using an electrochemical sensor based on polyepinephrine/glassy carbon electrode, PEP/GCE. Modification of GCE with PEP was done by electropolymersation of epinephrine, EP, in 0.2 M phosphate buffer solution using cyclic voltammetry, cv. A well-defined redox cv wave of epinephrine in potential range of -0.10 ...
