The erosion hindrance of carbon steel in 1M HCl in nearness and nonappearance of terminated Hydrocortisone Sodium Succinate has been examined utilizing mass-loss. Comes about gotten appeared that the restraint productivity expanded with the increment of the concentration of the utilized medicate and diminished with the increment of temperature. The adsorption of this sedate on carbon steel surface takes after Langmuir’s adsorption isotherm. A few thermodynamic parameters were calculated. The motor parameters of erosion of carbon steel in HCl arrangement have been examined. Keywords: Corrosion inhibition; Carbon steel; Hydrocortisone

Extracts from plant materials have great potential as alternatives to inorganic corrosion inhibitors, which typically have harmful consequences. Experimental and theoretical methodologies studied the effectiveness of agricultural waste, namely, date palm seed extract as a green anti-corrosive agent in 0.5 M hydrochloric acid. Experimental results showed that immersion time and temperature are closely related to the effectivity of date palm seed as a corrosion inhibitor. The inhibition efficiency reduced from 95% to 91% at 1400 ppm when the immersion time was increased from 72 h to 168 h. The experimental results also indicated that the inhibition efficiency decreased as the temperature increased. The presence of a protective layer of organic matter was corroborated by scanning electron microscopy. The adsorption studies indicated that date palm seed obeyed Langmuir adsorption isotherm on the carbon steel surface, and Gibbs free energy values were in the range of −33.45 to −38.41 kJ·mol−1. These results suggested that the date palm seed molecules interacted with the carbon steel surface through mixture adsorption. Theoretical calculations using density functional theory showed that the capability to donate and accept electrons between the alloy surface and the date palm seed inhibitor molecules is critical for adsorption effectiveness. The HOMO and LUMO result indicated that the carboxyl (COOH) group and C=C bond were the most active sites for the electron donation-acceptance type of interaction and most auxiliary to the adsorption process over the Fe surface.

Dodecylamine spontaneously adsorbs on carbon steel via its polar group (-NH2) in hydrochloric acid solution. Furthermore, it forms a monolayer film on carbon steel surface. The inhibition mechanism of dodecylamine for carbon steel is geometric blocking effect. The adsorption of dodecylamine on carbon steel surface follows Arrhenius equation. The adsorption slightly increases activated energy, but greatly reduces pre-exponential factor value. Atomic force microscopy force curves indicate that at the area without adsorbed dodecylamine, no obvious adhere force occurs. At the area with adsorbed dodecylamine, however, an average 1.3 nN adhere force is observed.

Kinetic Treatment

The inhibition of corrosion of mild steel in hydrochloric acid solutions by 2-benzoylpyridine (2BP) and pyridoxolhydrochloride (PXO) at 303K, 313K and 323K has been investigated using weight loss and hydrogen evolution techniques. 2BP exhibited higher maximum inhibition efficiency (78.99%) than PXO (71.93%). Generally inhibition was found to increase with increasing inhibitor concentration and decreasing temperature. A first order type of mechanism has been deduced from the kinetic treatment of the results and the process of inhibition was attributed to physisorption. The difference in the inhibition behaviour of the two compounds has been explained on the basis of structure dependent electron donor properties of the inhibitors
