The extraction of linseed oil (LO) was realized by refluxing method. The extracted oil was identified by gas chromatography method coupled with mass spectrometry (GC-MS). In order to contribute to the protection of the environment, one contemplates to try on LO as a green corrosion inhibitor. The corrosion inhibition of LO was studied by weight loss and electrochemical methods. The obtained results showed that the LO is an effective inhibitor of the carbon steel corrosion in 1[Formula: see text]M HCl solution, the inhibition efficiency increased with concentration to reach 88% at 200[Formula: see text]ppm. Furthermore, the adsorption of the inhibitor on the surface of metal in 1[Formula: see text]M HCl solution was found to obey Langmuir’s adsorption isotherm. The influences of temperature were also studied in the range from 298[Formula: see text]K to 328[Formula: see text]K. The kinetic and thermodynamic data of activation dissolution process were determined and discussed.

Corrosion Inhibition Efficiency

A new aromatic Schiff base with azo linkage (AS) has been synthesized and characterized by FT-IR, 1H NMR and 13C NMR spectroscopic techniques. The new compound (AS) has been evaluated as carbon steel corrosion inhibitor at different concentrations (0.005, 0.01, 0.02, 0.04 and 0.08 mM) and different temperatures (303 – 333 K). The corrosion inhibition efficiency was studied by potentiodynamic polarization and weight loss measurements. The effects of concentration and temperature on the inhibition efficiency were studied by potentiodynamic polarization studies, the results showed that increasing concentration of AS increases the inhibition efficiency while increasing the temperature decreases it, the highest corrosion inhibition efficiency, 93.9% was recorded with 0.08 mM of AS at 313 K in 1 M H2SO4. Weight loss measurements showed that the inhibition efficiency reached 97.1% in the presence of AS (0.08 mM) at 313 K. The adsorption process was found to obey Langmuir isotherm, and the adsorption thermodynamic parameters were studied. Scanning electron microscope (SEM) was used to confirm the results.

Palm oil (Elaeis guineensis) leaves extract was investigated on its potential to inhibit carbon steel corrosion via weight loss and potentiodynamic polarisation methods. Corrosion inhibition of carbon steel using palm oil leaves extract was determined at various temperatures, salinities, and concentrations. The inhibition efficiency increased with the increasing of inhibitor concentration but decreased with the rise in temperature. The highest inhibitor efficiency was 83.70% with a corrosion rate of 0.44 mm/yr which was obtained at zero salinity (in distilled water) with 25% of inhibitor concentration at 303 K. The results obtained proved that the extract solution from palm oil leaves can be used as an effective inhibitor of carbon steel in seawater.

This work focused on the use of natural, and eco-friendly waste material as an inhibitor for inhibiting carbon steel corrosion. In order to obtain minimum rate of corrosion on carbon steel, optimization of the process factors that affect carbon steel corrosion was undertaken using the Response Surface Methodology (RSM). Three parameters were fluctuated viz; temperature, pumpkin pod extract concentration and time of exposure and their corresponding effects on rate of corrosion of carbon steel were ascertained. The data obtained was fitted to a model that is quadratic which was subsequently validated. The predicted lowest rate of corrosion by the model is 2.5427mm/yr with optimal conditions of 178.07ppm of pumpkin extract concentration, exposure time of 2.26hrs, and 35.28oC of temperature. The conditions were validated in three replicates and corrosion rate of 2.75mm/yr was obtained. Keywords: corrosion, optimization, pumpkin pod, response surface methodology.
