摘要

Three anti-diabetic drug based biomolecules (Acarbose, Voglibose and Miglitol) were investigated for their corrosion inhibitive effect on mild steel in 700 ppm NaCl solution. Corrosion tests were conducted using weight loss measurements, electrochemical measurements, surface morphologies, quantum chemical studies and molecular dynamics simulation techniques. The results showed increasing corrosion inhibition efficiency with increasing concentrations of all studied biomolecules. The addition of Zn ion (synergistic effect) increased the inhibition of Acarbose, Voglibose and Miglitol on mild steel to a considerable extent. The anodic mode of inhibition mechanism was proposed for the effect of examined inhibitors, as revealed by Tafel polarization technique. Adsorption process of all the investigated inhibitors on the mild steel surface obeys the Langmuir adsorption isotherm. The surface morphologies of the mild steel were studied using SEM and EDXA. The experimental results are well correlate with the quantum chemical and molecular dynamics simulation results. The trend of corrosion protection efficiency of the drug based biomolecule is Ac > Vo > Mi as observed from experimental, theoretical and simulation studies.
