Resumo: Improper disposal of contaminated water into the environment has caused serious environmental problems for water bodies and soils. In order to reduce this problem, laws were created imposing limits on the amount of substances present in water before being discharged into the environment. Toluene has a very high pollutant potential due to its flammable, toxic and carcinogenic properties and even low concentrations need to be treated before disposal or reuse. Among the techniques offered for wastewater treatment, adsorption, using agricultural materials, stands out, which besides promoting a high percentage of removal has a low cost and high biodegradability. In this sense, this work aimed to evaluate the efficiency of cashew bagasse as a natural adsorbent for the removal of toluene in aqueous solution. The tests were performed in batch. Cashew bagasse dissolved substances that interfered with reading on the spectrophotometer. For this reason, a preliminary study was performed, resulting in a corrective method that disregards the interference of bagasse in the reading of the concentration of aliquots. The results showed a 77% removal. It was also observed that the removal percentage was higher for tests with higher initial solution concentration. The experimental data were better suited to Langmuir adsorption model and with maximum adsorption capacity of 49.02 mg toluene.g-1 of bagasse.

Para reducir este problema, se crearon leyes que imponen límites a la cantidad de sustancias presentes en el agua antes de ser vertidas al medio ambiente. El tolueno tiene un potencial contaminante muy alto debido a sus propiedades inflamables, tóxicas y cancerígenas, siendo necesario, incluso a bajas concentraciones, tratarlo antes de desecharlo o reutilizarlo. Entre las técnicas ofrecidas para el tratamiento de aguas residuales, destaca la adsorción, utilizando materiales agrícolas. Además de promover un alto porcentaje de eliminación, tiene un bajo costo y una alta biodegradabilidad. En este sentido, este trabajo tuvo como objetivo evaluar la eficiencia del bagazo de anacardo como un adsorbente natural para la eliminación de tolueno en solución acuosa. Las pruebas se realizaron en lote. Se descubrió que el bagazo de anacardo disuelve sustancias que interfieren con la lectura en el espectrofotómetro. Por esta razón, se realizó un estudio preliminar, que resultó en un método correctivo que ignora la interferencia del bagazo en la lectura de la concentración de alícuotas. Los resultados mostraron una eliminación del 77%. También se observó que el porcentaje de eliminación fue mayor para las pruebas con una concentración de solución inicial más alta. Los datos experimentales se adaptaron mejor al modelo de adsorción de Langmuir y con una capacidad de adsorción máxima de 49.02 mg de tolueno.g-1 de bagazo.O despejo indevido de águas contaminadas no meio ambiente tem provocado sérios problemas ambientais para corpos hídricos e solos. No intuito de reduzir esse problema, leis foram criadas impondo limites na quantidade de substâncias presentes na água antes de seu despejo no meio. O tolueno tem um potencial poluidor muito alto devido as suas propriedades inflamáveis, tóxicas e cancerígenas, sendo necessário, mesmo em baixas concentrações, o tratamento do mesmo antes de descarte ou reuso. Dentre as técnicas oferecidas para tratamento de águas residuais, destaca-se a adsorção, utilizando materiais agrícolas, que além de promover um alto percentual de remoção possui um baixo custo e alta biodegrabilidade. Nesse sentido, esse trabalho teve como objetivo avaliar a eficiência do bagaço de caju como adsorvente natural para remoção de tolueno em solução aquosa. Os ensaios foram realizados em batelada. Identificou-se que o bagaço de caju dissolvia substâncias que interferiam na leitura no espectrofotômetro. Por este motivo foi realizado um estudo preliminar, resultando num método corretivo que desconsidera a interferência do bagaço na leitura da concentração das alíquotas. Os resultados mostraram uma remoção de 77%. Observou-se ainda que o percentual de remoção foi maior para testes com maiores concentrações iniciais. Os dados experimentais adequaram-se melhor ao modelo de adsorção de Langmuir e com capacidade máxima de adsorção de 49,02 mg de tolueno.g-1 de bagaço.Editora Verde2020-04-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersiontext/htmlapplication/pdfhttps://www.gvaa.com.br/revista/index.php/RVADS/article/view/759410.18378/rvads.v15i2.7594Revista Verde de Agroecologia e Desenvolvimento Sustentável; Vol. 15 No. 2 (2020); 178 - 182Revista Verde de Agroecologia e Desenvolvimento Sustentável; Vol. 15 Núm. 2 (2020); 178 - 182Revista Verde de Agroecologia e Desenvolvimento Sustentável; v. 15 n. 2 (2020); 178 - 1821981-8203reponame:Revista Verde de Agroecologia e Desenvolvimento Sustentavelinstname:Grupo Verde de Agroecologia e Abelhas (GVAA)instacron:GVAAporhttps://www.gvaa.com.br/revista/index.php/RVADS/article/view/7594/7557https://www.gvaa.com.br/revista/index.php/RVADS/article/view/7594/7795Copyright (c) 2020 André Luís Oliveira Maia et al.info:eu-repo/semantics/openAccessMaia, André Luís OliveiraLeite, Ricardo Henrique de LimaSantos, Francisco Klebson Gomes2021-06-12T14:09:06Zoai:ojs.gvaa.com.br:article/7594Revistahttps://www.gvaa.com.br/revista/index.php/RVADS/PUBhttps://www.gvaa.com.br/revista/index.php/RVADS/oairvadsgvaa@gmail.com || patriciomaracaja@gmail.com || revistaverde1@gmail.com || suporte@antsoft.com.br1981-82031981-8203opendoar:2024-03-06T12:59:39.417124Revista Verde de Agroecologia e Desenvolvimento Sustentavel - Grupo Verde de Agroecologia e Abelhas (GVAA)false
