Carbon Black modified glassy carbon electrode for the detection of antioxidants compounds

In this paper we describe the use of Carbon Black (CB) as electrode modifier of the glassy carbon surface to achieve improved performance in terms of electrode stability, sensitivity and repeatability with respect to the naked glassy carbon electrode. The main advantage of the CB modified GC electrode with respect to other carbon electrode materials is the resistance to passivation which leads to the possibility of electrode reusing for tens of repeated measurements; thus avoiding electrode regeneration which represent the major limitation to 'real world' application of such approach.
