Egyptian Academic Journal of Biological Sciences has published a research by Dr. Hamida I. Salman, a professor at Faculty of Education for Pure Sciences / University of Kerbala.
The research is entitled Application and theoretical study: New Barbiturate Derivatives as Corrosion Inhibitors.
The study’s focus is on the use of potentiostat technology to stop the corrosion of mild steel alloys using various barbiturates which are newly prepared compounds. It has been synthesized and described by 13C, FTIR, and 1HNMR techniques at concentrations ranging from 0 to 200 ppm in a 1M sulfuric acid solution at temperatures between 303 and 323 K. Anode and cathode curves (a, c), corrosion current density (Icorr), corrosion potential (Ecorr), and efficiency inhibition ratio (E%) were used in the experiments, and the results were presented.DFT calculations have been performed to understand the nature of the interactions between the inhibitor molecules and the surface of the alloy to be tested.
The study has led to identification of a new barbiturate derivative using FT-IR, H-NMR1 and 13C-NMR techniques.
