“…This can be attributed to the increase in the number of chloride ions at the steel surface, as the NaCl concentration increases, which hinders lignin molecules adsorption onto the steel surface, thereby decreasing the inhibition efficiency. Similar observation has been reported in literature [7].…”

The inhibitive action of Chromolaena odorata stems extract, in various concentrations, against mild steel corrosion in a 1 M NaCl solution, was studied using weight loss, potentiodynamic polarization methods and scanning electron microscopy. Maximum inhibition efficiency of 99.83 % was obtained, at 303 K, for an extract concentration of 3000 mgL-1. The activation and free energies for the inhibition reactions supported the physical adsorption mechanism. The extract adsorption onto the mild steel surface was found to be exothermic, spontaneous, and to obey the Langmuir adsorption model. FT-IR analysis showed the presence of hydroxyl (OH) and carbonyl(C=O) functional groups and aromatic rings in lignin, which are the binding groups that might be responsible for lignin's inhibitive action against mild steel corrosion. Furthermore, SEM analysis revealed that the mild steel surface was affected by lignin's adsorption, due to the formation of a protective film.

“…Perhaps the most common natural substances used are plant extracts. Mild steel corrosion inhibition using different types of plant extracts has been investigated by many researchers [5][6][7][8][9][10][11][12][13][14]. Chromolaena odorata is an invasive deep-rooted shrub recorded as part of the 100 worst invasive species in the world [15].…”

“…Numerous researchers reported the successful use of natural plant extracts on the corrosion inhibition of mild steel in different media [12][13][14][15][16][17][18][19][20][21][22][23]. Most of these investigated plant extracts exhibit a moderate to high inhibition efficiency in the range 55-90% in acidic media.…”

A comparative study on the inhibitive effect of Crataegus oxyacantha and Prunus avium plant leaf extracts on the corrosion of mild steel in hydrochloric acid solution

The inhibitive action of plant leaf extracts, Crataegus oxyacantha (Hawthorn) and Prunus Avium (Sweet Cherry) on the corrosion of mild steel in 0.5 M HCl solution was investigated using open circuit potential-time measurements (OCP), potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) techniques. Functional groups of these plants' leaf extracts and their absorption bands were identified by Fourier transform infrared spectroscopy (FTIR) and Ultra-Violet Spectrophotometer (UV), respectively. The leaf extracts showed good inhibition efficiency in hydrochloric acid solution. Potentiodynamic polarization curves revealed that Crataegus oxyacantha and Purnus Avium plants leaves extracts acted as mixed type inhibitors. Theoretical fitting of different isotherms, Langmuir, Florry-Huggins and the kinetic-thermodynamic models was tested to describe the mode of inhibitors' adsorption on mild steel surface. UV spectra proved that the inhibiting action takes place through simple physical adsorption of the extracts molecules on mild steel surface.

“…Both nicotine and anabasine are well known to exert their insecticidal effect by interacting with nicotinic acetylcholine receptors (Shao et al, 2007;Glennon & Dukat, 2000). Anabasine is the major alkaloid in N. glauca (Hawley, 1977;Saitoh, Noma, & Kawashima, 1985;Abd-El-Khalek, Abd-El-Nabey, & Abdel-Gaber, 2012) and all alkaloidal effects of the plant are attributed to this compound (Keeler, Balls, & Panter, 1981;Lisko et al, 2013). In N. glauca, anabasine makes up 1.2% of the plant material in fruits and 1.1% of the plant material in leaves.…”

For several decades, Nicotiana glauca has been known for its content of the pyridine alkaloid, anabasine. The toxicological effects of this metabolite have been extensively studied, as opposed to its potential insecticidal activity. The anabasine content of leaves of N. glauca, collected from Malta, was 0.258 ± 0.0042% as determined by High Performance Liquid Chromatography. In the Pieris rapae larval bioassay, the median effective concentrations of anabasine and the alkaloid extract were 0.572 and 1.202 mg per larva, respectively. The presence of other interfering metabolites may have resulted in this elevated EC 50 for the crude extract. Anabasine is quoted to be a very toxic alkaloid not solely to insects, but also to other animals, and its use in minute concentrations in insect traps may well prove it to be an effective natural insecticide.
