The objective of this study is to experimentally evaluate the inhibition properties of Saccharumofficinarum extract in a 15% hydrochloric acidic media for stainless steel (SS-410). The gravimetric,UV spectroscopy, FTIR and surface morphological studies carried out using SEM, AFM and XRDrevealed that the S. officinarum extract protected the SS 410 steel in 15% hydrochloric acidic medium.Gravimetric analysis revealed maximum 95.92 % inhibition efficiency at 4 g/L inhibitor concentration.The computational studies (quantum chemical calculations) were further utilized to understand theconcept of chelation mechanism. The surface film formation and other 3D features of S. officinarumextract film over SS-410 surface was confirmed using AFM studies. Adsorption of S. officinarumextract over SS-410 surface followed Langmuir adsorption isotherm. It is clear from the theoreticaland computational studies that the S. officinarum extract acted as mixed type inhibitor by adsorptionof hybrid organic-inorganic inhibitor ingredients on SS-410. Thus, S. officinarum extract can developan efficient protective layer on SS-410 that has various industrial applications.
