Corrosive Inhibitive Study of Stainless Steel in Hydrochloric Acid Using Eco-Friendly Sesmum Indicum Oil
نویسندگان
چکیده
The inhibitive and adsorptive properties of Sesmum indicum eco-friendly oil for stainless steel corrosion in hydrochloric acid was investigated using weight loss technique as well as electrochemical technique. The result has proved that the oil is excellent inhibitor for stainless steel in hydrochloric acid. The inhibition efficiency of oil for stainless steel increased with increase the amount of oil. The mechanism of the oil on the surface of stainless steel was found to be spontaneous, exothermic and physical adsorption. The experimental data fitted well to Langmuir adsorption isotherms. Obtained results were justified from the galvanostatic polarization method.

Jatropha curcas leaves extract was tested as a green corrosion inhibitor for mild steel in aqueous hydrochloric acid solution using gravimetric and thermometric techniques. The results reveal that the inhibition efficiency vary with concentration of the leaf extract and the time of immersion. Maximum inhibition efficiency was found to be 95.92% in 2M HCl with 0.5 g/l concentration of the extrac...
متن کاملMaterials Selection for Use in Hydrochloric Acid
Hydrochloric acid (HCl) is an important mineral acid with many uses, including the pickling of steel, acid treatment of oil wells and chemical cleaning and processing. This acid is extremely corrosive and its aggressiveness can change drastically depending on its concentration, the temperature and contamination by oxidizing impurities. One of the most commonly encountered oxidizing impurities i...
