Abstract: The neutral red/montmorillonite/SnO2 chemical modified electrode prepared had a higher electroactivity and stability. In comparison with the bare SnO2 electrode, the diffusion coefficients of neutral red determined by thin-layer spectroelectrochemical methods in the interface of the montmorillonite film were reduced by four order of magnitude, but the peak currents in cyclic voltammograms were increased.
