Resumo: Activated carbon (AC) was produced from Bambusa vulgaris to evaluate its potential of methylene blue dye (MB) adsorption. AC was prepared by direct physical activation, using the water vapor as activating agent. It was characterized considering the gravimetric yield of AC, the pH point of zero charge, Boehm titration method, surface area, volume and pore diameter analysis and superficial morphology. The application of AC was performed with kinetic studies and adsorption isotherms by the Langmuir and Freundlich isotherm models. The material produced presented surface area of 684.69 m2 g-1, pH point of zero chargeof 7.32 and predominance of acidic groups on their surface. By the micrographs analysis it was possible to verify the development of the material porosity due to activation. The maximum adsorption capacity for the MB dye was 301.07 mg g-1 the Langmuir model presented the best adjustment. The AC obtained from Bambusa vulgaris presented excellent texture and adsorption properties are it was very efficient in MB dye adsorption.

O CA foi preparado mediante ativação física direta, utilizando como agente ativante o vapor d’água sendo caracterizado quanto ao rendimento gravimétrico em CA, pH do ponto de carga zero, método titulométrico de Boehm, análise de área superficial, volume e diâmetro dos poros e da morfologia superficial. Para aplicação do CA realizou-se estudos de cinética e isotermas de adsorção, tendo aplicados modelos de isotermas de Langmuir e Freundlich. O material produzido apresentou área superficial de 684,69 m2 g-1, pH do ponto de carga zero de 7,32 e predominância de grupos ácidos em sua superfície. Pela análise da micrografia foi possível verificar o desenvolvimento da porosidade do material devido à ativação. A capacidade máxima de adsorção para o corante AM foi de 301,07 mg g-1 com melhor ajuste ao modelo de Langmuir. O CA obtido a partir de Bambusa vulgaris apresentou excelentes propriedades texturais e adsortivas, sendo eficiente na adsorção do corante azul de metileno.Embrapa Florestas2019-03-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/166810.4336/2019.pfb.39e201801668Pesquisa Florestal Brasileira; v. 39 (2019)Pesquisa Florestal Brasileira; Vol. 39 (2019)1983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/1668/830https://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessMorais, Rayssa de MedeirosSantana, Gregório MateusCosta Lelis, Roberto CarlosPaes, Juarez BenignoSchueler, Maria Vanessa EggerMorbeck, Fernanda Lago2020-01-03T00:22:33Zoai:pfb.cnpf.embrapa.br/pfb:article/1668Revistahttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/PUBhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/oaipfb@embrapa.br || revista.pfb@gmail.com || patricia.mattos@embrapa.br1983-26051809-3647opendoar:2020-01-03T00:22:33Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
