| Popis: | Purpose Chemical and electrochemical measurements were used to study the corrosion inhibition of aluminium in distilled water using one of pyridine derivatives as corrosion inhibitor. Design/methodology/approach Corrosion inhibition of aluminum in distilled water was investigated in the absence and presence of different concentrations of 2,6-di methyl pyridine (DMP). Potentiodynamic polarization, open circuit potential and Fourier Transform Infrared Spectroscopy were employed. Findings Inhibition efficiency of 86 per cent is reached with 0.0187 M of DMP at 25°C. Potentiodynamic polarization showed that DMP behaves as mixed type inhibitor. The inhibitor obeyed the Langmuir adsorption isotherm. The value of ΔG°ads suggests physico-chemical adsorption of the inhibitor molecule on the aluminium surface. Originality/value This paper indicates DMP could be used as corrosion inhibitor to prevent the corrosion of aluminium in in distilled water. |
