Abstract: 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 degrees 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 in increase in the adsorption. the Langmuir-Freundlich equation was the best-fitted model for the experimental data.
