Abstract :

The inhibitive action of Antigonon Leptopus acid extract on the corrosion of mild steel in 1M H2SO4 was studied by using weight loss measurements. Results demonstrated that the extract of Antigonon Leptopus acts as an effective corrosion inhibitor in the 1M H2SO4 acid medium. The inhibition efficiency of AL increased with increase in concentration and temperature. Thermodynamic parameter such as negative free energy value revealed that the spontaneous adsorption of inhibitors onto the mild steel surface.
