An electrocatalytic, cobalt-phthalocyanine screen-printed carbon voltammetric sensor for the measurement of the antioxidant gallic acid in instant coffee

A disposable, low-cost, screen-printed carbon electrode (SPCE), modified with cobalt phthalocyanine (CoPC), has been successfully employed as a voltammetric sensor for the determination of gallic acid (GA) in coffee. The cyclic voltammetric (CV) behaviour of GA indicates that this antioxidant undergoes electrocatalyt...
