Corrosion Protection of Carbon Steel By Voltaren Drug in Acid Media and Theoretical Studies

Recently, the metal carbon steel dissolution n 0.2N HCl solution is protected by using 2-(2-(2, 6dichlorophenyl amino) phenyl) acetic acid using (EIS) measurements, potentiodynamic polarization, and (W. L). It is shown that these inhibitions are perfect corrosion inhibitiors for carbon steel protection. The adsorption of inhibitor of molecules on the carbon steel surface affects inhibitions activity were refer to the simple blocking. The results show that inhibitors play a mix-type inhibitor. The program of hyperchem-8 used in theoretical study of the voltaren drug the using molecular mechanics and semi-empirical calculation. The binding energy (Delta E-b), heat of formation (Delta H-F), and total energy (Delta E-tot.) of the voltaren is calculated using PM3 method at 298K. The is calculated bond length and vibration spectra of drug complex used PM3. The theoretical data are compared with experimental result that same with those found experimentally.
