dc.description.abstract	A new green polymeric material, polyacrylamide grafted with Okra mucilage, a natural grade polysaccharide, was tested as corrosion inhibitor for mild steel in 0.5M H 2SO 4 using gravimetric and electrochemical techniques. The inhibition efficiency was found to increase with increasing inhibitor concentration up to maximum 96.6% for 100ppm at 25°C. The effects of immersion time (3-72h) and temperature (25-65°C) on the inhibition of corrosion have also been discussed. The adsorption of this inhibitor on the mild steel surface obeys a Langmuir adsorption isotherm. The scanning electron micrographs of the inhibited specimens show smoothening of the surface. © 2012 Elsevier Ltd.
