A screen printed carbon electrode (SPCE) impregnated with the electrocatalyst 2,6-dichlorophenolindophenol lanthanum salt ([DCPI] 3 La)was constructed. Using cyclic voltammetry the electrochemical behaviour of SPCE, -SPEs and their catalytic effect towards ascorbic acid was investigated. A synthesis protocol ([DCPI] 3 La) and some identification studies are given. The fabrication of...
An ascorbate sensor based on a glassy carbon electrode modified with a cellulose acetate polymeric film bearing 2,6-dichlorophenolindophenol (CA/DCPI-CME) was constructed. The overall reaction obeys a catalytic regeneration mechanism (EC mechanism) and the electrochemical rate constant k f for the electrocatalytic oxidation of ascorbic acid was evaluated. The modified electrodes were mounted...
