【 摘 要 】

Dyes are widely used in various industries. It is significant to remove dye from wastewater before discharge. Adsorption onto activated carbon is more than beneficial than the other traditional methods as a result of its high adsorption capacity for coloured particle. The main objective of this study is to prepare activated carbon from elephant dung (EDAC). The adsorption performance of EDAC was studied by conducting batch adsorption experiments. The adsorption data are correlated with Langmuir and Freundlich under various conditions methylene blue (MB) concentration and contact time. The optimum dosage of EDAC was found to be 100 mg. EDAC adsorption was fitted with Langmuir model. The calculated maximum adsorption capacity was 18.98 mg/g. A dimensionless separation factor (RL) indicated a favourable adsorption of MB onto EDAC. The study indicates that EDAC could be employed as a cost-effective alternative adsorbent for removing MB from wastewater streams. EDAC also was cheap, more eco-friendly and effective waste utilization.
