The electrochemical behavior of Kraft Lignin Glassy Carbon Modified electrodes, GCE-LIG, was studied. The modified electrode was prepared by recovering the glassy carbon surfaces with 10 μL of 1.0 and 0.01 g L-1 lignin in DMF. The polymeric film produced showed electrochemical activity due the quinone / hydroquinone (Q/HQ) redox couple produced from lignin by a mechanism involving an electrochemical oxidation step followed by a coupled chemical reaction. The GCE-LIG is stable at negative potentials up to - 1.5 V in pH range of 2.0 to 8.0, but the lignin polymeric film is leached from the electrode surface at potentials higher than + 0.8 V. The modified electrodes showed resistive behavior, which increased with the film thickness. Another interesting characteristic of the GCE-LIG is its selectivity to coordination complexes since the electrochemical activity increases as function of the major complexes lability.
