Dyes are known to be toxic, carcinogenic and mutagenic. Their release into the environment can cause aesthetic pollution, and moreover, they are not degraded by conventional aerobic wastewater treatment due to their recalcitrance. Therefore, it is necessary to reduce dye concentration in the wastewater. Activated carbon was obtained from capsicum straw by chemical activation using KOH as an activator. Then it was used as an adsorbent for the removal of dye methylene blue. The adsorption of dye methylene blue by activated carbon was carried out in detail. Kinetic adsorption data were analysed by the pseudo-first-order kinetic model, the pseudo-second-order model and the intraparticle diffusion model. The experimental data were analysed by the Langmuir and Freundlich models of adsorption. The thermodynamics parameters were also calculated.Keywords

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
