In the present work, Pyrrole derivatives containing oxygen, nitrogenand aromatic rings namely,N-(1H-Pyrrol-2-ylmethylidene)-2,3-dihydro-1,4-benzodioxin-6-amine (BPS) was synthesized and its anticorrosion potential was studied applying the gravimetric, polarization and AC impedance methods on the mild steel (MS) corrosion in corrodent (0.5M H2SO4 and 1 M HCl). It is observed that in the acidic environments, the inhibition efficiency (IE) of the BPS raised with the enhance in the concentration and it resulted in greater inhibition efficiency in1 M HCl solution than in 0.5M H2SO4 solution. The inhibition efficiency assessed by Electrochemical Impedance Spectroscopy reaches about 81.6% in 0.5 M H2SO4 and 84.2% in 1.0 M HCl solutions at 600 ppm of BPS.The studied BPS being mixed type inhibitor was shown by the Tafel polarization curves. And it was noticed that over the MS surface, the adsorption of the BPS obeyed Langmuirisotherm. In order to ascertain the inhibitor mechanism, the potential of zero charge (PZC) was measured. Electrochemical Impedance spectroscopy was applied to assess the influence of temperature on corrosion inhibition.The surface morphology of MS surface was analyzed using SEM and AFM techniques. The anti-bacterial activity for the BPS was studied as a divergent analysis.
