In this work, the inhibition effect of corrosion inhibitor was studied on carbon steel corrosion in boiler. The inhibition effect of N,N′-bis(2,4,6-trihydroxyacetophenone)-2,2-dimethylpropandiimine (THAPDP) as a Salen Ligand corrosion inhibitor on carbon steel was investigated in alkaline solution (pH=10) containing 3% NaCl using electrochemical and surface techniques. Experimental results suggested that this compound was an effective corrosion inhibitor for mild steel and the protection efficiency was increased with the increase in inhibitor concentration. The experimental results indicated that this organic compound was a mixed-type inhibitor. Adsorption on the mild steel surface followed the Langmuir isotherm model. Activation parameters and thermodynamic adsorption parameters of the corrosion process such as Ea, ΔH, ΔS, Kads, and ΔGads were calculated at different temperatures.
