ELECTROOXIDATION OF 2,4,6-TRICHLOROPHENOL ON GLASSY CARBON ELECTRODES MODIFIED WITH COMPOSITE Ni(OH)2-Co(OH)2 FILMS

Glassy carbon electrodes coated with a film of electrodeposited cobalt and nickel hydroxides were prepared in order to determine its activity to the 2,4,6-trichlorophenol (TCP) oxidation. The modified electrodes were characterized by cyclic voltammetry (CV), electrochemical impedance spectroscopy (E...
