Corrosion Mitigating Effect ofCyamopsis TetragonalobaSeed Extract on Mild Steel in Acid Medium

摘要

The role of seed extract ofCyamopsis tetragonalobaon corrosion mitigation of mild steel in 1 M HCl has been investigated by weight loss method and potentiodynamic polarization technique. Maximum inhibition efficiency ofCyamopsis tetragonalobain 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.
