The role of seed extract of Cyamopsis tetragonaloba on corrosion mitigation of mild steel in 1 M HCl has been investigated by weight loss method and potentiodynamic polarization technique. Maximum inhibition efficiency of Cyamopsis tetragonaloba in 1 M HCl was found to be 92%. Experimental results were fitted into Langmuir and Temkin adsorption isotherm to study the process of inhibition. The potentiodynamic polarization results reveal that the seed extract behaved like mixed type inhibitor.
