Título: | Chemical composition of the copper/benzotriazole interface in the presence of acetic acid vapour at low humidities |
Autor: | Cano Díaz, Emilio CSIC ORCID ; Bastidas, David M. CSIC ORCID; Simancas Peco, Joaquín CSIC; López Caballero, Javier Ángel; Bastidas Rull, José María | Fecha de publicación: | 2004 | Editor: | Multi Science Publishing | Citación: | Adsorption Science and Technology 22: 565-582 (2004) | Resumen: | Studies were made of the chemical composition of the copper products formed at 43, 58 and 78% relative humidity (RH) in contaminated (10-ppm acetic acid vapour) and uncontaminated environments in the presence and absence of the volatile corrosion inhibitor benzotriazole (BTA) for 7 d at 30°C. Such studies were conducted using X-ray photoelectron spectroscopy (XPS). General XPS spectra over a wide binding energy region showed C and O peaks in addition to those corresponding to the different copper compounds. Copper specimens exposed to acetic acid vapour in the presence of BTA also exhibited N emissions. The main compounds formed were cuprite (Cu2O), copper hydroxide [Cu(OH 2], copper acetate and copper-benzotriazole (Cu-BTA) complexes. | URI: | http://hdl.handle.net/10261/76547 | DOI: | 10.1260/0263617042879447 | Identificadores: | doi: 10.1260/0263617042879447 issn: 0263-6174 |
