What is it about?
Researchers have discovered that cysteine, an amino acid, can be used as an effective and green corrosion inhibitor for mild steel in sulfuric acid. The study utilized potentiodynamic polarization and electrochemical impedance spectroscopy to determine that cysteine acts as a mixed-type inhibitor, with an inhibition efficiency of up to 70%. Furthermore, the researchers used density functional theory calculations and Monte Carlo simulations to investigate the electronic structure and inhibition mechanism of cysteine. Molecular adsorption on Fe2O3 surface (110) was also studied using Monte Carlo Simulation. This study provides valuable insights into the potential use of cysteine as a green corrosion inhibitor, which could have practical applications in various industries.
