Corrosion inhibition behavior of Ketosulfone for Zinc in acidic medium

N Hebbar, BM Praveen, BM Prasanna, TV Venkatesha

Abstract



The corrosion inhibition behavior of Ketosulfone for zinc is investigated by polarization and AC-impedance techniques at 303-333K. The Tafel plots indicates that the Ketosulfone is a mixed type inhibitor. The interaction between metal and inhibitor is explained by Langmuir adsorption isotherm.  DG0ads andDH0ads value indicates the electrostatic interactions between metal and inhibitor. Calculated activation parameters explains the corrosion process. SEM images show the difference between inhibited solutions and blank solution.

Keywords: corrosion inhibitor; adsorption; Langmuir isotherm; Zinc.
