| dc.description.abstract | The objective of this study was to investigate the potential of Persea americana (avocado) seed extract as a corrosion inhibitor in potable water distribution systems. The extract, which was readily soluble in water, was obtained by soaking powder of P. americana seeds in acetonitrile. FT-1R was employed to analyze functional groups present in the extract. Furthermore, electrochemical impedance spectroscopy and potentiodynamic polarization techniques were used in this study to find the inhibitive behavior of P. americana seed extract using potable water as an electrolyte at pH ranging from 4 - 7. The inhibition efficiency of P. americana seed extract was found to increase with an increase in inhibitor concentration up to 87% for EIS and 91% for potentiodynamic polarization measurements using 250 ppm. The inhibitor was found to be more efficient as the pH values were increasing. The adsorption of the inhibitor on mild steel under stationary conditions at 303 K was found to obey Langmuir adsorption isotherm. Findings from this study reveal the potential of P. americana seed extract as a corrosion inhibitor for the mild steel in potable water distribution systems. | en_US |
