Polarographic Studies for the Corrosion of Carbon Steel in Hydrochloric Acid Solutions
Main Article Content
Abstract
The present work deals with the quantitative corrosion determination of carbon steel in hydrochloric acid by the use of polarographic and weight loss technique.
The polarographic peak obtained at (-0.27 v) in 0.1 M hydrochloric acid was used for the determination of iron and a calibration was ranged (10-5–10-3) M.
To confirm the obtained results a weight loss measurement were carried out, its results are in good agreement with that of the polarographic measurements. The research included in addition to that a kinetic study of corrosion reactions of iron in hydrochloric acid. Reaction rates were calculated at different temperature, and apparent energies of activation have been calculated from corrosion rates and Arrhenius plots.
