Abstract:
In the present study, we have synthesized two
novel corrosion inhibitors BP-1 and BP-2 and evaluated their
corrosion inhibition property on mild steel (MS) in acid
solution through weight loss and electrochemical corrosion
techniques. The corrosion test results reveal that both
compounds inhibit corrosion by an adsorption mechanism
and display inhibition efficiency more than 95% at a low
concentration of 1.72 × 10−4 M. From the surface analysis of
the protective film on MS, it was corroborated that adsorption
of inhibitor molecules occurred on the MS surface through
chemisorption, which further suppresses the corrosion rate.
Density functional theory simulated data helps correlate the experimental trend with the theoretical study
