Abstract
In this study, the effectiveness of various types of charcoal, including pine, olive, and commercial activated carbon, as adsorbents for removing methylene blue dye from water is evaluated. The study was conducted by preparing aqueous solutions containing methylene blue dye and using the three types of charcoal as adsorbents. The main factors affecting the adsorption process were determined through laboratory experiments, which included varying temperature, contact time, pH, and the quantity of charcoal to optimize the dye removal process. Additionally, isotherm studies and thermodynamic analysis of the reaction were conducted. The results demonstrate the successful removal of methylene blue dye by all three types of charcoal, with maximum adsorption capacities of 346.02 mg/g, 283.28 mg/g, and 406.50 mg/g for commercial activated carbon, olive charcoal, and pine charcoal, respectively. The ΔH results indicate that the adsorption process for pine charcoal and activated carbon was physical, while it was chemical for olive charcoal. This research highlights the efficiency, costeffectiveness, and sustainability of the adsorption process using charcoal as a promising solution for reducing dye pollution in water sources, contributing to the development of sustainable water purification strategies
