Abstract
The role o f 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 o f 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.
