چکیده مقاله :
The high concentrations of various industrial pollutants in atmospheric waters present a significant environmental challenge due to their widespread occurrence and high resistance to degradation. Therefore, the development of low-cost and eco-friendly methods, such as the production of new biosorbents, is essential. In this study, three commonly used types of sawdust—Walnut, Russian, and Forest wood—were utilized to produce different biosorbents for the removal of the anionic dye methyl orange from contaminated water. The effects of various physical and chemical activation methods on the adsorption capacity of these biosorbents were examined. The produced biosorbents were characterized using FTIR and SEM analyses, and the results were compared. Additionally, Langmuir, Freundlich, and Sips isotherms were employed for the isotherm studies. Based on the reported results, biosorbents with pore sizes of less than 1 µm and the highest adsorption capacities of approximately 800 mg/g were produced from all three types of sawdust studied after the pyrolysis process. However, a comparison between produced biosorbents show the samples derived from Russian sawdust exhibited relatively higher adsorption capacities of 80, 380, and 760 mg/g after solvent extraction, chemical activation, and pyrolysis processes. In addition, the maximum adsorption capacities were achieved in minimum adsorbent dose of 0.01 g per 100 ml of solution. Among all the studied isotherms, the Sips model, with R² values close to one, was found to be the best-fitting isotherm.
