In order to assess the impact of 1-((2, 4-dimethylphenyl) diazenyl) naphthalen-2-ol (DPN) on carbon steel deterioration in a 1M HCl environment, potentiodynamic polarization methods were employed. The findings of the electrochemical assessment highlighted a correlation between DPN concentration and inhibition efficiency. Further analysis using potentiodynamic polarisation methods identified DPN as a mixed-type determent. The adhesion of DPN on the metallic exterior was evaluated using Langmuir Adhesion Isotherm, and thermodynamic parameters just like ΔG°ads, ΔH°ads, and ΔS°ads were studied. The impact of temperature on deterioration rate was also evaluated, with testing conducted at 298, 308, and 318 absolute temperature. Lastly, the synthesis and characterisation of the DPN compound was completed. Spectroscopic ways like FT-IR, 13C NMR, and 1H NMR were utilised.
