Abstract
The effect of using Conocarpus extract as a green inhibitor on the corrosion behavior of mild steel in a 1M HCL environment was investigated by electrochemical impedance spectroscopy (EIS), potentiodynamic polarization (PDP), scanning electron microscopy (SEM), and Fourier-transform infrared spectroscopy (FTIR). The impedance test showed that the polarization resistance increased from 29 for the blank solution to 299 for the solution containing 2500 ppm of Conocarpus extract. The results of the polarization test showed that at room temperature, the corrosion current density for the blank solution decreased from 3.5E-4 to 2.6E-5for the solution containing 2500 ppm of Conocarpus extract, and the potential was shifted to negative values. The polarization test was performed at three temperatures of 25, 55, and 85. The results showed that the efficiency of 1925 ppm has decreased from 93% at room temperature to 86% at 85 ° C. Obviously, the high-temperature efficiency has not reduced significantly, which means the effectiveness of Conocarpus extract at high temperatures. FTIR test also proved that the corrosion inhibitory effect of Conocarpus extract is due to the presence of heteroatoms such as N, S, and O. The adsorption isotherm results showed that the adsorption of the extract as a single layer on the surface is consistent with the Langmuir isotherm.
Highlights
- The effect of Conocarpus extract on corrosion of mild steel in 1 M HCl medium was investigated.
- Corrosion parameters including corrosion current density, polarization resistance, surface coverage, etc. were obtained by electrochemical impedance, potentiodynamic polarization methods.
- The effect of temperature on the corrosion behavior of mild steel in solution containing Conocarpus extract was investigated. Conocarpus extract was able to maintain its inhibitory properties at high temperatures.
- The inhibitory properties of Conocarpus extract are due to the presence of heteroatoms of N, S, O and their adsorption on the surface.
