Aqueous Extract of Cumaru (Dipteryx odorata) Seeds as Corrosion Inhibitor for Mild Steel in Hydrochloric Acid Solution

Investigation 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...

Turmeric extract as a biocompatible inhibitor of mild steel corrosion in 3.5% NaCl solution

Corrosion inhibitory impacts of turmeric with concentrations of 200-800 ppm on the electrochemical behavior of mild steel were studied in the medium of NaCl 3.5% using several techniques such as electrochemical impedance spectroscopy (EIS) and polarization. Scanning electron microscopy (SEM) was used for analyzing the surface of mild steel after 24 hours of immersion in the electrolyte solution...

Investigation on Ethylenediaminetetra-Acetic Acid as Corrosion Inhibitor for Mild Steel in 1.0M Hydrochloric Acid

electrochemical and quantum chemical calculations of two schiff bases as inhibitor for mild steel corrosion in hydrochloric acid solution

the corrosion inhibition characteristics of two synthesized schiff bases, namely n, n´-bis(2-hydroxy-6-nitrobenzaldehyde) benzidine  and n, n´-bis(salysylaldehyde) benzidine, on the mild steel corrosion in 2.0 m hydrochloric acid have been investigated by weight loss, potentiodynamic polarization and electrochemical impedance spectroscopy techniques. these studies were carried out at different ...
