Abstract: Conducting polymers have emerged as effective adsorbents in the field of waste water treatment due to their cost effectiveness and higher environmental stability. The present investigation deals with the application of Polyaniline, a potential conducting polymer, for the removal of a toxic textile dye (Methyl Orange), from wastewater. The applied adsorbent, Polyaniline has been synthetically prepared by chemical oxidative polymerization of aniline with doping of an organic acid (oxalic acid). Batch studies were conducted to determine the effect of several influential parameters such as pH, amount of adsorbent, contact time and concentration at different temperatures. Preliminary adsorption studies revealed that maximum decolorization occurred at pH 3 after 5 hours of contact time. Almost 92% Methyl Orange removal was achieved at 50°C with 0.03 g of the adsorbent. Studies revealed the efficiency of polyaniline for the removal of methyl orange from waste water
