Abstract

), indicating spontaneous adsorption involving both physical and chemical interactions. The effect of temperature was evaluated over the range of 298-328 K, where the inhibitors maintained relatively high inhibition efficiencies, although a slight decrease was observed with increasing temperature. Surface analysis further confirmed the formation of a protective adsorbed film on the mild steel surface. Overall, the combined findings highlight the potential of sulfonamide-based compounds, particularly SAP5, as effective corrosion inhibitors for mild steel in acidic environments.
