Adsorption mechanisms of methylene blue and methyl orange on activated carbon: scientific interpretation and modeling simulation (opens in new tab)

Activated carbon was produced from olive waste to investigate the adsorption behavior of methylene blue (MB) and methyl orange (MO) dyes in aqueous solutions. The adsorbent was characterized using X-ray diffraction and scanning electron microscopy, and adsorption isotherms were measured at three different temperatures. A statistical physics framework was employed to analyze the adsorption mechanisms of the dyes on the carbon surface. The steric, energetic, and thermodynamic characteristics of...
