Abstract
Sulphanilic acid (4-amino benzene sulphonic acid) is a commercially very important aromatic compound.  The literature revealed that the chemical and physical properties of sulphanilic acid had been explored much. In the present study cyclic voltammetric studies of sulphanilic acid is concentrated.  The working electrodes used were platinum and glassy carbon. To visualize the influence of pH on the anodic oxidation of sulphanilic acid cyclic voltammograms were recorded in acidic, neutral and alkaline conditions.  Scan rate variation studies and multiple scan studies were also done. From these studies it found that sulphanilic acid is susceptible for anodic oxidation and the process is diffusion controlled on platinum electrode and is not forming any polymer on the electrode surface.
