Voltametric Characterization of Composite Silicon-Carbon Electrode in Presence of Indigo Carmine

The fight against pollution by heavy metals requires the establishment of reliable and inexpensive simple techniques. Electrochemical sensors offer innovative solutions provided you have active materials sensitive layer. This layer must have in his surface selective groups facing metallic cations. More organo-mineral composite materials are used in electroanalysis. Here silicon is incorporated into the carbon graphite conductive matrix. The silicon-carbon composite material has active sites in electroanalysis in the presence of indigo carmine.
