It was carried out using nanoparticles (particles) as a photocatalyst. <100 nm) of titanium dioxide (TiO2 Degussa P25); since a nanometer size has a large surface area with a greater number of atoms on its surface, requiring less energy (photons) to perform electronic jumps, that is why the activity of the photocatalyst increases when the particles of this have a nanometric size. The objective of this investigation was the degradation of azoic dye: orange II or acid orange 7, commonly used in the textile industry, using heterogeneous photocatalysis, one of the advanced oxidation processes; the experiments were performed using TiO2 Degussa P25, where the photocatalytic reaction takes place inside the photoreactor which consisted of a 30 cm spiral tube placed on a curved mirror to concentrate the solar radiation for 3 hours. The results show that the photocatalysis has been very effective for the removal of the azoic dye worked at a concentration of 100ppm, obtaining a removal greater than 90%. The variables investigated were: concentration of the catalyst (100-600 mg / L), concentration of hydrogen peroxide (0-2 ml / L) and time (0-3 hours); the concentration of orange dye II was determined by spectrophotometry visible at 485 nm. to find the conditions of greatest influence on the degradation of the dye. This work shows the importance of the use of nanoparticles for the different applications; Among the main ones: in medicine as a drug vehicle, in electronics for data storage, in impressions and sensors and other electronic devices, in the production of hydrogen, in self-cleaning surfaces and as environmental catalysts for water and air, paintings and photocatalytic cements , among others; that can contribute to help us solve the problems that afflict us today.","PeriodicalId":199715,"journal":{"name":"Las tramas del modernismo","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130763864","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
