Mentha spicata L. Extract as a Green Corrosion Inhibitor for Carbon Steel in HCl Solution
The effect of Mentha spicata L. extract on the corrosion behaviour of carbon steel in 1.0 M HCl solution was investigated using polarization, electrochemical impedance spectroscopy (EIS) and electrochemical noise (EN) techniques. The solution containing 250 ppm of the ethanolic solution of extract showed the highest inhibition efficiency (IE). The effect of temperature on the rate of corrosion ...
متن کاملInvestigation of Furfural as Corrosion Inhibitor in Hydrochloric Acid Solution
Effectiveness of furfural as an organic inhibitor in 5 percent hydrochloric acid which is used in acid pickling of steel was evaluated. Lungmuir, Frumkin and Flory-Huggins isotherms [1, 2] were used to determine the parameters of effective adsorption, free energy and entropy of adsorption. Furfural indicated an inhibition less than 17 percent in concentrations of 0.001 mole per liter for a dura...
متن کاملEthoxylated fatty amines as corrosion inhibitors for carbon steel in hydrochloric acid solutions
The effect of three compounds of non ionic surfactants, namely, ethoxylated fatty amines with different number of ethylene oxide unit on the corrosion of carbon steel (Type L52) in 1 M HCl has been studied using weight loss and galvanostatic polarization measurements. The percentage inhibition efficiency was found to increase with increasing concentration of inhibitor, number of ethylene oxide ...

متن کاملMalvasylvestris Flower Extracts as Green Corrosion Inhibitor for Carbon Steel in HCl Solution
In this study, Malvasylvestris flower extract (MFE) was used as a corrosion inhibitor for carbon steel in 1 M HCl solution. Malvasylvestris extract was analyzed by gas chromatography coupled with a mass spectrometry detector (GC-MS). Potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) studies revealed that the inhibition efficiency increases with increasing MFE concent...
