The textile industry plays an important role in the economies of numerous countries around the world. But the dye wastewater from the textile industry has become one of the most serious environmental problems today for its harm, especially in aquatic environments. Dyes are aromatic organic colorants and have potential applications in textile, plastic, rubber, paper and food industries. Therefore, the treatment of dye wastewater is of interest. The potential and effectiveness of the camphor sawdust was studied as an alternative adsorbent for the removal of dye wastewater. The dye Congo red was used as the pollutant. The effects of camphor sawdust dosage, pH in aqueous solution, the contact time and dye Congo red concentration on dye Congo red adsorption by the camphor sawdust were investigated. The results showed that the reaction factors had an important influence on adsorption process. The adsorption isotherm fitted better with the Langmuir model and the adsorption process was an endothermic process. The maximum adsorption capacity obtained from the Langmuir isotherm is 29.51 mg/g.Keywords
