    Adsorption characteristics of Croton sparsiflorus Leaves extract on corrosion of Mild steel in acidic media
    (2016) Prithiba, A; Thilagavathi
    The inhibition efficiency of leaves extract of Croton sparsiflorus{CSL) on corrosion of mild steel ini M HCI was carried out by mass loss and electrochemical techniques. To understand the nature of the adsorption process, thermodynamic and kinetic parameters were evaluated using temperature studies results, A maximum of 98 % inhibition efficiency was obtained for 0.7% concentration of CSL. Influence of temperature on the corrosion inhibitive nature of CSL was also studied. Thermodynamic parameters demonstrated that the inhibition was due to spontaneous adsorption of inhibitor on the metal surface. The inhibitor was found to follow Langmuir and Temkin adsorption isotherms. Electrochemical studies confirmed that CSL acted as mixed type inhibitor. Surface analytical studies further ascertained the inhibitive nature of the inhibitor.
