Resumo: | The present work aimed to develop a composite based on cellulose, melamine and silica. Cellulose was obtained from the pruning residues of Mangifera indica for the chemically assisted primary treatment of effluents from the textile industry. The composite was characterized by FT-IR, SEM, TEM, TGA-DTG and Zeta Potential. The central composite planning was applied to optimize the composite mass and contact time in removing methylene blue. FT-IR showed that the composite presented the band for melamine at 815 cm-1. SEM and TEM revealed that on the composite surface there is melamine nitrogen, silicon and sodium from the catalyst. TGA-DTG showed that the composite is thermally more stable than cellulose, with 65% degradation. Due to the zeta potential, pH values above 5 provide greater stabilization and increase the anionic character of the composite. It was chosen as the best condition for the application 60 mg of composite and 30 minutes of contact time, with removal of 88.6 ± 3.5% of the methylene blue. The pH study revealed that above 5, the composite is more efficient. The dye adsorption process by the material was consistent with the Langmuir model (R2 = 0.9921). Thus, the cellulose-melamine-silica composite developed was effective in removing the methylene blue dye, presenting itself as a low-cost, biodegradable and efficient material, with potential for application in the treatment of effluents from the textile industry. |

La celulosa se obtuvo de los residuos de poda de Mangifera indica para el tratamiento primario asistido químicamente de efluentes de la industria textil. El compuesto se caracterizó por FT-IR, MEV, MET, TG-DTG y Zeta Potential. Se aplicó la planificación central del compuesto para optimizar la masa del compuesto y el tiempo de contacto para eliminar el azul de metileno. FT-IR mostró que el composite presentaba la banda de melamina a 815 cm-1. SEM y MET revelaron que en la superficie compuesta hay nitrógeno de melamina, silicio y sodio del catalizador. TG-DTG demostró que el material compuesto es térmicamente más estable que la celulosa, con un 65% de degradación. Debido al potencial zeta, los valores de pH superiores a 5 proporcionan una mayor estabilización y aumentan el carácter aniónico del material compuesto. Se eligió como la mejor condición para la aplicación de 60 mg de composite y 30 minutos de tiempo de contacto, con remoción del 88,6 ± 3,5% del azul de metileno. El estudio de pH reveló que por encima de 5, el compuesto es más eficiente. El proceso de adsorción del tinte por el material fue consistente con el modelo de Langmuir (R2 = 0.9921). Así, el compuesto de celulosa-melamina-sílice desarrollado fue eficaz para eliminar el colorante azul de metileno, presentándose como un material de bajo costo, biodegradable y eficiente, con potencial de aplicación en el tratamiento de efluentes de la industria textil.Este trabalho objetivou desenvolver um compósito a base de celulose, melamina e sílica. A celulose foi obtida dos resíduos de poda da Mangifera indica para o tratamento primário quimicamente assistido de efluentes da indústria têxtil. O compósito foi caracterizado por FT-IR, MEV, MET, TG-DTG e Potencial Zeta. O planejamento composto central foi aplicado para otimização da massa de compósito e tempo de contato na remoção de azul de metileno. O FT-IR mostrou que o compósito apresentou a banda para a melamina em 815 cm-1. O MEV e MET revelaram que na superfície do compósito há Nitrogênio da melamina, Silício e Sódio oriundos do catalisador. O TG-DTG mostrou que o compósito é termicamente mais estável que a celulose, com 65% de degradação. Pelo potencial zeta, valores de pH acima de 5 propiciam maior estabilização e incremento do caráter aniônico do compósito. Escolheu-se como a melhor condição para a aplicação 60 mg de compósito e 30 minutos de tempo de contato, com remoção de 88,6 ± 3,5% do azul de metileno. O estudo do pH revelou que acima de 5, o compósito é mais eficiente. O processo de adsorção do corante pelo material apresentou-se coerente ao modelo de Langmuir (R2 = 0,9921). Assim, o compósito de celulose-melamina-sílica desenvolvido foi eficaz na remoção do corante azul de metileno, apresentando-se como um material de baixo custo, biodegradável e eficiente, com potencialidades para a aplicação no tratamento dos efluentes da indústria têxtil.Research, Society and Development2021-05-20info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1533110.33448/rsd-v10i6.15331Research, Society and Development; Vol. 10 No. 6; e3710615331Research, Society and Development; Vol. 10 Núm. 6; e3710615331Research, Society and Development; v. 10 n. 6; e37106153312525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/15331/13830Copyright (c) 2021 Jarbas Soares de Mesquita Júnior; Francisco Cardoso Figueiredo; Evânia Carvalho dos Santos; Darlisson Slag Neri Silva; José Ribeiro dos Santos Júniorhttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessMesquita Júnior, Jarbas Soares de Figueiredo, Francisco CardosoSantos, Evânia Carvalho dosSilva, Darlisson Slag NeriSantos Júnior, José Ribeiro dos2021-06-10T22:51:46Zoai:ojs.pkp.sfu.ca:article/15331Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:36:10.966949Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
