Page 1-7
Abstract
The effects of Enantia chlorantha (ET) stem bark ethanoic extract on the corrosion of Mild steel in acids environment and acid basicity to concentration ratio on the electrochemical corrosion behavior of Enantia chlorantha on mild steel in acid environments was studied using electrochemical techniques. The results showed that ET is a good inhibitor of Mild steel corrosion acids media. The Potentiodynamic polarization results showed Enantia chlorantha (ET) stem bark ethanoic extract to act as a mixed-type corrosion inhibitor while the Electrochemical Impedance results showed the extract increased the charge transfer resistance and increased the double layer capacitance, attributing the corrosion inhibition process of Enantia chlorantha (ET) stem bark ethanoic extract to adsorption of its molecules on the Mild steel/acid interface. However, it was concluded that the basicity of the acid is an important factor on the inhibition performance. Hence need to balance it in order to achieve desired corrosion inhibition targets.
