In conclusion we have found that it is posibble the formation of polymer of ANS, when the electroxidation of monomer is carried out in PANI/Au or carbon paste electrodes. The films obtained are electrochemically active in neutral pH. The charge compensation of this film is carried out principally by ejection of cation, but anion insertion is simultaneuslly presented. On other hand, the electrochemical polymerization of luminol in carbon paste electrodes give a film with characteristic of a seld-doped polymer contraty to the film obtained using metallic electrodes which are dimmers. A polymer was synthetised to luminol and ANS, the cyclic voltammogram obtain show peak intermediate beetween luminol and ANS, the film can catalize the oxidation of aa and is electroachemically active to neutral pH, the proportion of monomers in the film can be modulate by the solution composition and the scan rate.
