A study assessing plant extracts as green corrosion inhibitors is important because of the potential cost effective and environmental benefits. This study employed a strategy to evaluate the effectiveness these molecules against corrosion of mild steel in acid media. Many plant extracts have been used as corrosion inhibitors of iron or steel in acidic media. This research aims to examine the effects of commercial oil of Eucalyptus on inhibition of corrosion with mild steel in hydrochloric acid by means of gravimetric, potentiodynamic polarization and electrochemical impedance spectroscopic measurements. The results of the polarization curves show that the corrosion current density decreases from 3618 A/cm 2 to 87 A/cm 2 with the addition of the Eucalyptus inhibitor. The charge transfer resistance increases from 17 Ohm•cm 2 to 185 Ohm•cm 2 in the electrochemical impedance spectrum after the addition of the oil Eucalyptus inhibitor in the more concentrated solutions It is found that the adsorption of our green inhibitor on steel surface obeys the Langmuir adsorption isotherm equation. The inhibition efficiency was found to be increased with increasing immersion time of samples in the solution. The polarization plots indicate that the studied Eucalyptus inhibitor affects both the anodic metal dissolution, and the catholic hydrogen evolution acting as a mixed type inhibitor.

This work presents a phytochemical study of selected plants extracts to evaluate their potential synergistic corrosion inhibition performance. It was observed that the dominant phytochemicals derived from ten plant leaves and seeds can be synergies in group to enable better understanding of their inhibitory mechanism, which is a potentially significant gap in knowledge. Based on the results of phytochemical screening using FTIR, GC-MS, VU-VIS, and further analysis of the active and predominant phytochemicals, their reaction complex, inhibitor compatibility and other physical and chemical properties as reported in literature, the plant extracts have been grouped into three Organic Green Corrosion inhibitor (OGCI) formulations. Group 1-Greentreat-1234, Group 2-Greentreat-95627 and Group 3-Greentreat-85. The inhibitor adsorption is via, Pie -bond orbital adsorption, Electrostatic adsorption, Chemisorption and Physisorption as reported in literature. The implication of this study is that OGCI has the potential to control wet corrosion of carbon steel.

“…One of the renowned ways of controlling and reducing the corrosion rate of the low carbon steel is to apply organic inhibitors [15,[20][21][22][23][24][25][26][27]. These organic corrosion inhibitors are either simple or mixtures that are added to the aggressive environments in low quantities in order to reduce, control or even hinder reactions from occurring between the metal and its surroundings [28].…”

The inhibiting effect of Gum Arabic-nanoparticles (GA-NPs) to control the corrosion of reinforced concrete that exposed to carbon dioxide environment for 180 days has been investigated. The steel reinforcement of concrete in presence and absence of GA-NPs were examined using various standard techniques. The physical/surface changes of steel reinforcement was screened using weight loss measurement, electrochemical impedance spectroscopy (EIS), atomic force microscopy and scanning electron microscopy (SEM). In addition, the carbonation resistance of concrete as well screened using visual inspection (carbonation depth), concrete alkalinity (pH), thermogravimetric analysis (TGA), SEM, energy-dispersive X-ray spectroscopy (EDX) and X-ray diffraction (XRD). The GA-NPs inhibitor size was also confirmed by transmission electron microscopy (TEM). The results obtained revealed that incorporation of 3% GA-NPs inhibitor into concrete inhibited the corrosion process via adsorption of inhibitor molecules over the steel reinforcement surface resulting of a protective layer formation. Thus, the inhibition efficiency was found to increase up-to 94.5% with decreasing corrosion rate up-to 0.57 × 10−3 mm/year. Besides, the results also make evident the presence of GA-NPs inhibitor, ascribed to the consumption of calcium hydroxide, and reduced the Ca/Si to 3.72% and 0.69% respectively. Hence, C-S-H gel was developed and pH was increased by 9.27% and 12.5, respectively. It can be concluded that green GA-NPs have significant corrosion inhibition potential and improve the carbonation resistance of the concrete matrix to acquire durable reinforced concrete structures.
