Resumo: | Motivated by technological and environmental needs, membrane separation processes have shown a great improvement over traditional techniques. These benefits encourage the application of membrane separations and stimulate development in purification and sterilization processes in the pharmaceutical and food industries in general. In addition, they are used in the water treatment for industrial or urban use, desalination, gas separation, clarification of juices, hemodialysis and in the effluents treatment. The latter is the application that this work is intended for, especially in the separation of water from textile dyes, i.e., indigo blue. Thus, polysulfone membranes were synthesized in the form of hollow fiber, with varying levels of alumina, for use in the effluents treatment. The morphological characteristics, hydrophilicity, flow measurements and the turbidity measurement of the prepared membranes were evaluated. The membranes were produced by the phase inversion method, via cold extrusion, immersion - precipitation. Filtration experiments indicate that alumina particles can increase the flow of water by improving the hydrophilicity of the membrane. By SEM images, a larger amount of pores, of smaller sizes, was verified with the insertion of alumina in the polysulfone. Thus, through the analysis of the Turbidimeter, the amount of indigo blue particles suspended in the membrane with alumina was smaller, since the pores are smaller and their greater quantity, generating a greater removal of the dye. Thus, with the increase in the alumina content, the separation between water and the indigo blue dye was improved. |

Estos beneficios fomentan la aplicación de separaciones por membranas y estimulan el desarrollo de procesos de purificación y esterilización en la industria farmacéutica y alimentaria en general. Además, se utilizan en el tratamiento de aguas para uso industrial o urbano, desalación, separación de gases, clarificación de jugos, hemodiálisis y en el tratamiento de efluentes. Esta última es la aplicación a la que está destinado este trabajo, especialmente en la separación de agua de tintes textiles, es decir, azul índigo. Así, se sintetizaron membranas de polisulfona en forma de fibra hueca, con niveles variables de alúmina, para su uso en el tratamiento de efluentes. Se evaluaron sus características morfológicas, hidrofilia, medidas de flujo y medidas de turbidez. Las membranas fueron producidas por el método de inversión de fase, vía extrusión en frío, inmersión - precipitación. Los resultados obtenidos por filtración indican que las partículas de alúmina pueden incrementar el flujo de agua mejorando la hidrofilia de la membrana. Por SEM se verificó una mayor cantidad de poros, de menor tamaño, con la inserción de alúmina en la polisulfona. Así, a través del análisis del Turbidímetro, la cantidad de partículas de azul índigo suspendidas en la membrana con alúmina fue menor, ya que los poros de estas son más pequeños y en mayor cantidad, generando una mayor remoción del tinte. Así, con el aumento del contenido de alúmina, se mejoró la separación entre el agua y el colorante azul índigo.Motivado pelas necessidades tecnológicas e ambientais, os processos de separação por membranas têm exibido uma grande melhora em relação às técnicas tradicionais. Estes benefícios incentivam a aplicação de separações por membranas e estimulam o desenvolvimento em processos de purificação e esterilização nas indústrias farmacêutica e alimentícia, em geral. Além disso, elas são utilizadas no tratamento de água para uso industrial ou urbano, dessalinização, separação de gases, clarificação de sucos, hemodiálise e no tratamento de efluentes. Esta última, é a aplicação que este trabalho se destina, especialmente na separação de água dos corantes têxteis, isto é, o índigo blue. Dessa forma, foram sintetizadas membranas de polisulfona na forma de fibra oca, com teores variados de alumina, para uso no tratamento de efluentes. Foram avaliadas as características morfológicas, a hidrofilicidade, as medidas de fluxo e a medida de turbidez delas. As membranas foram produzidas pelo método da inversão de fase, via extrusão a frio, imersão - precipitação. Os resultados obtidos por filtração indicam que as partículas de alumina podem aumentar o fluxo de água melhorando a hidrofilicidade da membrana. Por MEV, foi verificada uma maior quantidade de poros, de tamanhos menores, com a inserção da alumina na polisulfona. Desse modo, por meio da análise do Turbidímetro, a quantidade de partículas suspensas de índigo blue na membrana com alumina foi menor, visto que os poros destas são menores e em maior quantidade, gerando uma maior remoção do corante. Assim, com o aumento do teor de alumina, foi melhorada a separação entre a água e o corante índigo blue.Research, Society and Development2021-01-07info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1086310.33448/rsd-v10i1.10863Research, Society and Development; Vol. 10 No. 1; e18610110863Research, Society and Development; Vol. 10 Núm. 1; e18610110863Research, Society and Development; v. 10 n. 1; e186101108632525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/10863/10391Copyright (c) 2021 Arthur Felipe Pereira da Silva ; Edcleide Maria Araújo ; Hélio de Lucena Lira; Rodholfo da Silva Barbosa Ferreira; Vanessa da Nóbrega Medeiros; Sandriely Sonaly Lima Oliveirahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessSilva , Arthur Felipe Pereira da Araújo , Edcleide Maria Lira, Hélio de Lucena Ferreira, Rodholfo da Silva Barbosa Medeiros, Vanessa da Nóbrega Oliveira, Sandriely Sonaly Lima 2021-02-20T21:19:23Zoai:ojs.pkp.sfu.ca:article/10863Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:32:50.012497Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
