Resumo: The textile industry is responsible for the generation of highly colored effluents, which need adequate treatment. Thus, the advanced oxidative processes (AOP) have been used to degrade the dye and convert organic matter. In the present study, the degradation of the reactive blue dyes BF-5G and red remazol RB 133% were evaluated through Fenton and photo-Fenton processes (solar and sunlight). To determine the best working condition, the pH, peroxide concentration, iron concentration and time variables were evaluated by performing a kinetic study in this condition. From a preliminary study, it was verified that the Fenton and photo-Fenton processes, using different radiations, presented similar results, reaching a degradation of more than 98% for each dye. The factorial design indicated better results for a concentration of H2O2 of 10 mg . L-1, iron concentration of 5 mg . L-1 and time of 15 min, obtaining degradation above 88% for the studied dyes. A good kinetic adjustment was verified for a pseudo first order kinetic model (R2 = 0.9921 and 0.9867 for blue and red dyes, respectively). Ultimately, the study of chemi-cal oxygen demand indicated a conversion of 75.98% for the Fenton process, 86.63% photo-Fenton solar and 87.02% photo-Fenton sunlight.

Nesse sentido, os processos oxidativos avançados (POA) têm sido empregados para degradar o corante e converter a matéria orgânica. No presente trabalho avaliou-se a degradação dos corantes azul reativo BF-5G e remazol vermelho RB 133% via processos Fenton, foto-Fenton (solar e sunlight). Para identificação da melhor condição de trabalho foram avaliadas as variáveis pH, concentração de peróxido, concentração de ferro e tempo; sendo realizado estudo cinético nesta condição. A partir de um estudo preliminar verificou-se que os processos Fenton e foto-Fenton, empregando diferentes radiações, apresentaram resultados semelhantes, alcançando uma degradação superior a 98% para cada corante. O planejamento fatorial indicou melhores resultados para uma concentração de H2O2 de 10 mg.L-1, concentração de ferro de 5 mg.L-1 e tempo de 15 min, obtendo degradação acima de 88% para os corantes estudados. Um bom ajuste cinético foi verificado para um modelo cinético de pseudo primeira ordem (R2 = 0,9921 e 0,9867 para os corantes azul e vermelho, respectivamente). Por fim, o estudo da demanda química de oxigênio indicou uma conversão de 75,98% para o processo Fenton, 86,63% foto-Fenton solar e 87,02% foto-Fenton sunlight.Universidade Federal de Santa Maria2017-10-08info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/reget/article/view/2735810.5902/2236117027358Revista Eletrônica em Gestão, Educação e Tecnologia Ambiental; REGET, V. 21, N. 2, MAY-AUG., 2017; 104-118Revista Eletrônica em Gestão, Educação e Tecnologia Ambiental; REGET, V. 21, N. 2, MAIO-AGO., 2017; 104-1182236-11702236-1170reponame:Revista Eletrônica em Gestão Educação e Tecnologia Ambiental (REGET)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMenghttps://periodicos.ufsm.br/reget/article/view/27358/pdfCopyright (c) 2017 Electronic Journal of Management, Education and Environmental Technology (REGET)http://creativecommons.org/licenses/by-nc-sa/4.0info:eu-repo/semantics/openAccessSantana, Rayany Magali da RochaNascimento, Graziele Elisandra doNapoleão, Daniella CarlaDuarte, Marta Maria Menezes Bezerra2022-08-09T19:03:51Zoai:ojs.pkp.sfu.ca:article/27358Revistahttps://periodicos.ufsm.br/regetPUBhttps://periodicos.ufsm.br/reget/oaimarcelobdarosa@gmail.com||reget.ufsm@gmail.com2236-11702236-1170opendoar:2022-08-09T19:03:51Revista Eletrônica em Gestão Educação e Tecnologia Ambiental (REGET) - Universidade Federal de Santa Maria (UFSM)false
