HEC was investigated as efficient corrosion inhibitor for mild steel in 1 M HCl.
Synergistic effect of surfactants on inhibition behavior of HEC was also investigated.
Methods used for investigation are Gravimetric, electrochemical, AFM and SEM-EDX.
Quantum chemical and UV–vis analysis furthur explain the adsorption process of HEC.
HEC acts as a mixed-type inhibitor.
