Elimination of a cationic dye in aqueous solution by adsorption on activated carbon: Optimization of analytical parameters, modeling and thermodynamic study

Abstract: Adsorption techniques are widely used to remove certain classes of pollutants from waters, especially those that are not easily biodegradable. The aim of this study was to evaluate the adsorption of Methylene Blue (MB) dye onto activated carbon from aqueous solutions was realized in a batch system. However, some examined factors such as contact time, pH solution, initial concentration of MB, adsorbent dosage and temperature were found to have significant impacts on the adsorption capacity of AC. The AC was cha… Show more

“…After carbonization, pine sawdust was chemically activated using KOH to improve the surface area and porosity trying to enhance dye adsorption. The exceptional adsorption capacity of activated carbons is mainly due to the well-developed porous structure, pore size distribution, and the presence of distinct functional groups [23]. Thus, in the present research, the production of activated carbons from a wood waste is proposed in an attempt to find environmentally friendly substitutes for commercial activated carbons to remove wood dyes from wastewaters.…”

“…Therefore, it is responsible for health risks such as damage to the nervous system, brain, and liver. 5 Many treatments have been undertaken to decrease the dye concentrations in water such as adsorption techniques, [6][7][8][9][10][11][12][13][14] biological treatment, 15 discoloration and detoxification, 16 photocatalytic deg radation, 17,18 and electrochemical degradation. 19 Among treatment strategies, adsorption is an effective method for removing pollutants from wastewater; it is inexpensive, with a simple design and high removal efficiency.…”
