Benzylidene Schiff Base Corrosion Inhibition and Electrochemical Studies of Mild Steel in 1M HCI and 0.5M H2SO4 Acidic Solutions

N ̶ Benzylidene 4 Methoxyaniline (NB4MA) schiff base was synthesized and investigated corrosion behavior of mild steel (MS) in 1M HCI 0.5M H2SO4. The efficiency studied by means mass loss electrochemical techniques. studies confirm that Ecorr displacement about 32mV confirms anodic cathodic type inhibitor. positive direction potential curves confirmed adsorption on metal surface. Langmuir isotherm observed. Electrochemical impedance (EIS) exposed inhibition effectiveness enlarged with even increasing concentration Schiff found capacity 90 – 95%. Furthermore, thermodynamic parameters were which elaborates ΔG0ads parameter since favorable interaction between inhibitor causes efficient adsorption. morphology revealed has strong affinity to adhere improve against acidic media. quantum chemical also electrons distribution base.
