Cysteine As An Eco-Friendly Corrosion Inhibitor, Hany A. Elazab Dr
Chemical Engineering
In this paper, the aim was finding the most efficient corrosion inhibitor for mild steel placed in a 0.5M Sulfuric acid. The comparison was implemented between Cysteine (an eco-friendly corrosion inhibitor) and 4 different Ions-Cysteine Inhibitors (Copper- Cysteine, Nickel-Cysteine, Iron-Cysteine, and Cobalt-Cysteine). The solutions were prepared and evaluated while placed with a working electrode of mild steel with a copper rod attached to its end. To determine the best eco-friendly corrosion inhibitors two experiments were implemented: Electrochemical Impedance Spectra, and Linear Polarization. By the end of the experiment it was found that Copper- Cysteine was the most efficient eco-friendly corrosion …
