Resumo: | Textile industry uses dyes in the dyeing processes, generating effluents with potential toxicity to the environment and humans, if not treated adequately. Biosorption is an alternative for removing dyes from aqueous matrices, being a low-cost and effective technique, also allowing the use of agroindustrial wastes. Therefore, this work aimed to evaluate the capacity to remove the direct scarlet red dye using cassava bagasse as a biosorbent, a waste widely generated in Brazil. The biosorbent was characterized according to its specific surface area. Initially, preliminary tests were performed to obtain the best conditions of pH, temperature, and speed of rotation. Kinetic and adsorption equilibrium tests were performed. Mathematical modeling was employed in order to understand the mechanisms involved in the adsorption of the dye. The cassava bagasse had a specific surface area of 3.012 m² g-1, with the presence of micropores. The batch biosorption tests obtained optimal operating conditions at pH 2, 50 °C and 90 rpm. In kinetics, removal of 84% was achieved in 300 min. In adsorption isotherms, the maximum monolayer adsorption capacity estimated by the Langmuir model was 25.1 mg g-1. In mathematical modeling, both Pseudo-first order, Pseudo-second order and Elovich models represent kinetic data, suggesting the occurrence of more than one mechanism in the process, whereas, in isotherms, the Redlich-Peterson and Toth models suggest a trend to the Freundlich model. In general, cassava bagasse proved to be an efficient adsorbent in removing the textile dye. |

La biosorción es una alternativa para la remoción de colorantes de matrices acuosas, siendo una técnica de bajo costo y efectiva, permitiendo también el uso de residuos agroindustriales. Por lo tanto, este trabajo tuvo como objetivo evaluar la capacidad de eliminar el tinte rojo escarlata directo utilizando bagazo de yuca como biosorbente, un residuo ampliamente generado en Brazil. El biosorbente se caracterizó en términos de su superficie específica. Inicialmente se realizaron pruebas preliminares para obtener las mejores condiciones de pH, temperatura y velocidad de rotación, y posteriormente se realizaron pruebas de equilibrio cinético y de adsorción. Se empleó un modelo matemático para comprender los mecanismos involucrados en la adsorción del tinte. El bagazo de yuca tuvo una superficie específica de 3.012 m² g-1, con presencia de microporos. Las pruebas de biosorción por lotes obtuvieron condiciones óptimas de funcionamiento a pH 2, 50 ° C y 90 rpm. En cinética, se logró una eliminación del 84% en 300 min. En las isotermas de adsorción, la capacidad máxima de adsorción de monocapa estimada por el modelo de Langmuir fue de 25,1 mg g-1. En el modelado matemático, los modelos de Pseudo-primer orden, Pseudo-segundo orden y Elovich representan datos cinéticos, lo que sugiere la ocurrencia de más de un mecanismo en el proceso, mientras que en las isotermas, los modelos de Redlich-Peterson y Toth sugieren una tendencia al Freundlich modelo. En general, el bagazo de yuca demostró ser un adsorbente eficaz para eliminar el tinte en estudio.A indústria têxtil faz uso de corantes nos processos de tingimento, gerando efluentes com potencial tóxico ao meio ambiente e seres humanos, se não tratados adequadamente. A biossorção é uma alternativa para remoção de corantes de matrizes aquosas, sendo uma técnica de baixo custo e efetiva, possibilitando ainda, o uso de resíduos agroindustriais. Portanto, esse trabalho objetivou avaliar a capacidade de remoção do corante vermelho escarlate direto utilizando como biossorvente o bagaço de mandioca, um resíduo amplamente gerado no Brasil. O biossorvente foi caracterizado quanto a sua área específica superficial. Inicialmente, testes preliminares foram realizados para obter as melhores condições de pH, temperatura e velocidade de rotação, e posteriormente, foram realizados testes cinéticos e de equilibrio de adsorção. A modelagem matemática foi empregada a fim de compreender os mecanismos envolvidos na adsorção do corante. O bagaço de mandioca apresentou área superficial específica de 3,012 m² g-1, com presença de microporos. Os ensaios de biossorção em batelada, obtiveram condições ótimas de operação em pH 2, 50 °C e 90 rpm. Na cinética, em 300 min obteve-se remoção de 84%. Nas isotermas de adsorção, a capacidade máxima de adsorção em monocamada estimada pelo modelo de Langmuir foi de 25,1 mg g-1. Na modelagem matemática, ambos os modelos de Pseudo-primeira ordem, Pseudo-segunda ordem e Elovich, representam os dados cinéticos, sugerindo ocorrência de mais de um mecanismo no processo, enquanto nas isotermas, os modelos de Redlich-Peterson e Toth sugerem uma tendência ao modelo de Freundlich. Em geral, o bagaço de mandioca mostrou-se um adsorvente eficiente na remoção do corante em estudo.Research, Society and Development2021-04-04info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1396410.33448/rsd-v10i4.13964Research, Society and Development; Vol. 10 No. 4; 16510413964Research, Society and Development; Vol. 10 Núm. 4; 16510413964Research, Society and Development; v. 10 n. 4; 165104139642525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/13964/12534Copyright (c) 2021 Ingridy Alessandretti; Regiane Ribeiro de Jesus ; Sumaya Ferreira Guedes ; Raquel Aparecida Loss ; Juliana Maria de Paula; Claudineia Aparecida Queli Geraldihttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessAlessandretti, IngridyJesus , Regiane Ribeiro de Guedes , Sumaya Ferreira Loss , Raquel Aparecida Paula, Juliana Maria de Geraldi, Claudineia Aparecida Queli2021-04-25T11:21:26Zoai:ojs.pkp.sfu.ca:article/13964Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:35:11.788571Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
