Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 49 N° 8 (Avril 2010) . - pp. 3986–3991 Titre : Cigarette butts and their application in corrosion inhibition for N80 steel at 90 °C in a hydrochloric acid solution Type de document : texte imprimé Auteurs : Jun Zhao, Auteur ; Ningsheng Zhang, Auteur ; Chengtun Qu, Auteur Année de publication : 2010 Article en page(s) : pp. 3986–3991 Note générale : Industrial Chemistry Langues : Anglais (eng) Mots-clés : Cigarette  Corrosion  Inhibition  Steel  Hydrochloric  Acid Résumé : Cigarette butts, one of the most ubiquitous forms of garbage in the world, need to be recycled because their toxicity can kill saltwater and freshwater fish. In this study, the cigarette butts are applied as corrosion inhibitors for N80 steel at 90 °C in hydrochloric acid. Weight loss and electrochemical techniques are used to evaluate the corrosion inhibitive effect of cigarette butt water extracts. Results show that the inhibition efficiencies arrive at 94.6% and 91.7% in 10% and 15% (wt %) HCl solution, respectively, by adding 5% (wt %) inhibitor. In 20% HCl solution, they show a maximum inhibition efficiency of 88.4% by adding 10% inhibitor.

Comparison of the corrosion inhibitive effect of anaerobic and aerobic cigarette butts water extracts on N80 steel at 90 °C in hydrochloric acid solution / Jun Zhao in Industrial & engineering chemistry research, Vol. 49 N° 24 (Décembre 2010) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 49 N° 24 (Décembre 2010) . - pp. 12452-12460 Titre : Comparison of the corrosion inhibitive effect of anaerobic and aerobic cigarette butts water extracts on N80 steel at 90 °C in hydrochloric acid solution Type de document : texte imprimé Auteurs : Jun Zhao, Auteur ; Ningsheng Zhang, Auteur ; Chengtun Qu, Auteur Année de publication : 2011 Article en page(s) : pp. 12452-12460 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Steel  Extract  Aerobe  Anaerobe  Corrosion Résumé : The chemical compositions of cigarette butts water extracts mainly are aromatic amines including nicotine and its compounds. If oxygen exists, the aromatic amine compounds can be oxidized easily. Whether this oxidation would be beneficial in enhancing the corrosion inhibitive effect of the inhibitor is not known. In this study, the corrosion inhibitive effect of aerobic and anaerobic cigarette butts water extracts are compared on N80 steel at 90 °C in 15% (weight %) hydrochloric acid. The chemical compositions of the aerobic and anaerobic cigarette butts water extracts are also contrasted. Weight loss, X-ray diffraction, and electrochemical techniques (such as electrochemical noise, impedance, and potentiodynamic polarization) are used to evaluate the corrosion inhibitive effect of aerobic and anaerobic cigarette butts water extracts. Results show that the inhibition efficiency of the aerobic cigarette butts water extracts (92.9%) is higher than anaerobic cigarette butts water extracts (84.6%).

Synergized action of CuCI on recycled cigarette butts as corrosion inhibitor for N80 steel at 90 °C in 15% HCl / Juantao Zhang in Industrial & engineering chemistry research, Vol. 50 N° 12 (Juin 2011) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 50 N° 12 (Juin 2011) . - pp. 7264-7272 Titre : Synergized action of CuCI on recycled cigarette butts as corrosion inhibitor for N80 steel at 90 °C in 15% HCl Type de document : texte imprimé Auteurs : Juantao Zhang, Auteur ; Jun Zhao, Auteur ; Ningsheng Zhang, Auteur Année de publication : 2011 Article en page(s) : pp. 7264-7272 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Steel  Corrosion  inhibitor Résumé : One of effective ways to reduce pollution from cigarette butts is introduced by recycling the cigarette butts. Inhibitor from recycled cigarette butts shows good inhibition properties, but we do not know whether CuCl can help to improve the inhibition efficiency. So, in this study, the impact of CuCl on recycled cigarette butts as corrosion inhibitor for N80 steel at 90 °C in 15% HCl is studied by weight loss, electrochemical noise, polarization, impedance, and X-ray photoelectron spectroscopy. All the results show that the inhibition efficiency of water extracts from cigarette butts in the presence of CuCl is higher than in absence of CuCl, and it can reach 95.3% when 9% water extracts with copper added is used. The X-ray photoelectron spectroscopy results indicate that the N80 steel specimen surface is undamaged and covered with a protective coat formed by copper-added water extracts from cigarette butts. CuCl has synergizing action on recycled cigarette butts as a corrosion inhibitor for N80 steel at 90 °C in 15% HCl.
