Electro chemical comparative studies of ortho, meta and para nitro phenols

Nitro phenol exists in three isomeric forms namely ortho, meta and para nitro phenols.  Their susceptibility for electrochemical oxidation was studies by cyclic voltammetric method and polarization studies.  Plenty of chemical studies are available in the literature. But a very little work has been done on the electrochemistry of nitro phenols. In the present study electrochemical approach was made to compare ortho, meta and para nitro phenols.  The cyclic voltammograms were recorded using platinum working electrode.   Polarisation studies were also done using platinum working electrode to find out the decomposition potential of the nitrophenols.  From these studies it is found that ortho and para nitro phenols are susceptible for electro oxidation but meta nitrophenol is not susceptible for the same.
