Resumo: Textile industries have environmental problems due to high levels of COD and color. Adsorption is one of the most important processes used to remove color from effluent. Adsorption isotherms of Remazol Gold Yellow Remazol RNL reactive dye in activated carbon were determined. Two parameters were studied: temperature (30 and 40°C) and particle size (1.70 ± 0.30 mm e 3.00 ± 0.40 mm). Results show that an increase in temperature or a decrease in particle size promotes an increase in the adsorption. The Langmuir-Freundlich equation was the best-fitted model for the experimental data.

Os processos de coagulação e adsorção são os mais utilizados na remoção de corantes têxteis. Neste trabalho foram determinadas as isotermas de adsorção do corante reativo Remazol Amarelo Ouro RNL em carvão ativado de casca de coco. Foram estudadas duas variáveis: temperatura (30 e 40ºC) e tamanho de partícula (1,70 ± 0,30 mm e 3,00 ± 0,40 mm). Os resultados mostraram que o aumento na temperatura ou a diminuição do diâmetro das partículas promove aumento na adsorção. O modelo de Langmuir-Freundlich apresentou melhor ajuste entre os modelos testados.Universidade Estadual De Maringá2009-06-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionmeio ambienteapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciTechnol/article/view/131010.4025/actascitechnol.v31i2.1310Acta Scientiarum.
