Resumo: | Environmental pollution has been a point of discussion in the international community and an object of investigation by research groups, which focus on the development of remediation methods. In the current study, the bunch of açaí (Euterpe oleracea) was used as a precursor for the preparation of low-cost activated carbon in order to remove the dye 17 AY 17 from the aqueous solution. The synthesis was carried out at temperatures of 500, 600 and 700 °C, for 2.0 h in a muffle furnace. The kinetic and thermodynamic mechanism of the adsorption process of the acid yellow dye 17, and the effects of pH, contact time and initial concentration were investigated. Activated carbon carbonized at 700 °C had the highest adsorption capacity, about of 99.9% of removal of the AY. The adsorption capacity of AY 17 was slightly pH dependent with a maximum value at pH 2.0. The kinetic data show that the equilibrium time was 200 min, and the adsorption capacity of activated carbon was 99.9% at 50 mg L‒1 and 67.0% at 150 mg L‒1 of adsorbate, suggesting high adsorption capacity of the material, even in the presence of high dye concentration. The adsorption process of AY 17 is described by the pseudo-second order kinetic model, and the experimental adsorption isotherms are adjusted to the Freundlich model, indicating that the adsorption of AY 17 on activated carbon occurs with the formation of multilayers. The present study shows that this low-cost material has great potential for remediation of textile effluents. |

En el presente estudio, se utilizó el racimo de açaí (Euterpe oleracea) como precursor para la preparación de carbón activado de bajo costo, con el fin de eliminar el tinte amarillo ácido 17 (AY 17) en solución acuosa. La síntesis se llevó a cabo a temperaturas de 500, 600 y 700°C, durante 2,0 h en una mufla. El mecanismo cinético y termodinámico del proceso de adsorción del tinte AY 17, y los efectos del pH, el tiempo de contacto y la concentración inicial se investigaron utilizando el tipo de carbón activado con la mayor capacidad de remoción. El carbón activado a 700 °C tuvo la mayor capacidad de adsorción, con un 99,9% de remoción AY 17. La capacidad de adsorción del AY 17 fue ligeramente dependiente del pH, alcanzando un valor máximo a pH 2,0. Los datos cinéticos muestran que el tiempo de equilibrio fue de 200 min, y la capacidad de adsorción del carbón activado fue del 99,9% a 50 mg L-1 y del 67,0 % a 150 mg L-1 de adsorbato, sugiriendo una alta capacidad de adsorción del material, incluso en la presencia de una alta concentración de tinte. El proceso de adsorción de AY 17 se describe mediante el modelo cinético de pseudo-segundo orden, y las isotermas de adsorción experimentales se ajustan al modelo de Freundlich, lo que indica que la adsorción de AY 17 en carbón activado ocurre con la formación de multicapas. El presente estudio muestra que este material de bajo costo posee gran potencial para la remediación de efluentes textiles. A poluição do meio ambiente tem sido ponto de discussão na comunidade internacional e objeto de investigação por grupos de pesquisa, que têm buscado o desenvolvimento de métodos de remediação. No presente estudo, o cacho de açaí (Euterpe oleracea) foi utilizado como precursor de carvão ativado de baixo custo para a remoção do corante amarelo ácido 17 (AY 17) em solução aquosa. A síntese foi realizada nas temperaturas de 500, 600 e 700 ° C, por 2,0 h em forno mufla. O mecanismo cinético e termodinâmico do processo de adsorção do corante AY 17, e os efeitos do pH, tempo de contato e concentração inicial foram investigados para o carvão ativado com maior capacidade adsortiva. O carvão ativado carbonizado a 700 °C teve a maior capacidade adsortiva, cerca de 99,9% de remoção do AY. A capacidade de adsorção de AY 17 é ligeiramente dependente do pH, com um valor máximo em pH 2,0. Os dados cinéticos mostram que o tempo de equilíbrio é de 200 min, e a capacidade de adsorção do carvão ativado foi de 99,9% a 50 mg L‒ 1 e 67,0% a 150 mg L‒1 de adsorbato, sugerindo alta capacidade de adsorção do material, mesmo na presença de alta concentração de corante. O processo de adsorção de AY 17 é descrito pelo modelo cinético de pseudo-segunda ordem, e as isotermas experimentais de adsorção são ajustadas ao modelo de Freundlich, indicando que a adsorção de AY 17 no carvão ativado ocorre com a formação de multicamadas. O presente estudo mostra que esse material de baixo custo possui grande potencial para remediação de efluentes têxteis.Research, Society and Development2022-01-22info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/2555610.33448/rsd-v11i2.25556Research, Society and Development; Vol. 11 No. 2; e16511225556Research, Society and Development; Vol. 11 Núm. 2; e16511225556Research, Society and Development; v. 11 n. 2; e165112255562525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/25556/22415Copyright (c) 2022 Deusimar de Oliveira Lopes; Lucas Oliveira Santos; Evair Dias Nascimento; Adriane Damasceno Vieira de Souza; Franscico Adriano de Oliveira Carvalhohttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessLopes, Deusimar de Oliveira Santos, Lucas Oliveira Nascimento, Evair DiasSouza, Adriane Damasceno Vieira deCarvalho, Franscico Adriano de Oliveira2022-02-07T01:42:50Zoai:ojs.pkp.sfu.ca:article/25556Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:43:48.832436Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
