Description
Summary:The effluents from the textile industry, which not properly treated or discharged directly into water bodies, are a serious environmental problem. In order to find options to solve this problem, in this study, it was evaluate two alternative adsorbents: red mud and smectite clay, to remove the dye Indosol dark-blue SF-BL SGR 240. Assays were performed in batch using the experimental design to optimize the process and evaluate the influence of pH, mass and agitation speed on the adsorption capacity of dye by each material. The results showed that the adsorption process was influenced by the amount of mass of the adsorbent, by the pH and the by interaction between pH and mass, thereby obtaining a removal of approximately 0.110 and 0.119 mg g −1 with red mud and smectite clay respectively.
