Experimental study shows effective corrosion inhibition by bis-DABCOnium salts in sulfuric acid, suggesting practical applications for steel protection.
Key Points
Corrosion inhibition efficiency of tested salts exceeded 95% at 298°K in 0.5M sulfuric acid, indicating strong protective capabilities.
Inhibitors were evaluated using gravimetric, electrochemical, and microscopy methods, confirming consistent effectiveness across techniques.
The adsorption behavior followed Langmuir adsorption isotherm, highlighting potential for practical steel applications in acidic environments.
The efficiency of inhibition decreased with temperature, indicating a temperature-dependent reaction mechanism for the inhibitors.
