APPLICATION OF COMPOSITES PHOTOCATALYSTS FOR THE DEGRADATION OF P-NITROFENOL IN WATER
The environmental responsibility forces us to look for adequate ways to treat contaminated watewater by organic compounds and provide alternatives to the generator industries. Therefore, this work is based on the degradation of p-nitrophenol (PNF) applying tio composites on activated carbon (CA/TiO)...

| description | The environmental responsibility forces us to look for adequate ways to treat contaminated watewater by organic compounds and provide alternatives to the generator industries. Therefore, this work is based on the degradation of p-nitrophenol (PNF) applying tio composites on activated carbon (CA/TiO). The photocatalyst was supported on carbon powder (CA1) and carbon in flakes (CA2) which are called composites in order to recover it. the compounds were characterized with ir spectrum and electronic scanning microscope. the degradation of the pollutant was evaluated with a UV-visible spectrophotometer. A UV light (λ = 365 nm) was used to irradiate the reactor and H2O2 was used as an oxidizing agent throughout the whole process time. Once the different trials have been studied using a completely randomized experimental design, it was observed that the combina tion of CA1 shows a high efficiency (99.1%) of removal of PNF in a concentrated aqueous solution (250mg.l-1) in an average time of 80 minutes. thus, CA2 presents a minor removal (50.46%) in an 80 minutes treatment. It might be concluded that CA1 presents a better complexation and efficiency in the PNF degradation. |

Por lo cual este trabajo se basa en la degradación de p-nitrofenol (PNF) aplicando compositos de dióxido de titanio (TiO) en carbón activado (CA/TiO). El fotocatalizador fue soportado sobre carbón en polvo (CA1) y carbón en escamas (CA2), llamados compositos, con el objeto de recuperarlo. Los compositos se caracterizaron con espectrofotómetro ir y microscopio de barrido electrónico. La degradación del contaminante fue evaluada con espectrofotómetro uv-visible. Para los ensayos con luz uv se utilizó una lámpara (λ = 365 nm) para irradiar el reactor durante todo el proceso y Ho como agente oxidante. Una vez estudiados los distintos ensayos usando un diseño experimental completamente aleatorio, se observó que la combinación de CA1 muestra una alta eficiencia (99,1%) de remoción de PNF en una solución acuosa concentrada (250mg l-1), en un tiempo medio de 80 minutos, pues ca2 presenta una remoción menor (50,46%) en 80 minutos de tratamiento. con esto se puede concluir que ca1 presenta un mejor acomplejamiento y eficiencia en la degradación de PNF.Escuela Superior Politécnica de Chimborazo2018-12-31info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionArtículo revisado por paresapplication/pdfhttps://perfiles.espoch.edu.ec/index.php/perfiles/article/view/3710.47187/perf.v2i20.37Perfiles; Vol. 2 No. 20 (2018): [July - December 2018]; 82-89Perfiles; Vol. 2 Núm. 20 (2018): [Julio-Diciembre 2018]; 82-892477-9105reponame:Revista Perfilesinstname:Escuela Superior Politécnica de Chimborazoinstacron:ESPOCHspahttps://perfiles.espoch.edu.ec/index.php/perfiles/article/view/37/15https://creativecommons.org/licenses/by-nc/4.0info:eu-repo/semantics/openAccess2024-03-22T18:08:15Zoai:ojs2.localhost:article/37Portal de revistashttps://perfiles.espoch.edu.ec/Universidad públicahttps://espoch.edu.ecEcuador2477-91051390-5740opendoar:02024-03-22T18:08:15Revista Perfiles - Escuela Superior Politécnica de Chimborazofalse |
