Insights into Equilibrium and Adsorption Rate of Phenol on Activated Carbon Pellets Derived from Cigarette Butts

In the present work, preparation of activated carbon pellets from cigarette butts by thermal treatment was evaluated. The morphological, textural, topological, and surface chemical properties were studied SEM-EDX, N2 adsorption, Raman, FTIR spectroscopy. For adsorption assays, tested for phenol as a model molecule at different solution pH, temperature, type water. addition, leaching tests before after carbonization conducted to evaluate lixiviation ions in solid. results revealed microporous material, composed cylindrical fibers (thickness 13 µm) with area 713 m2/g narrow uniform slit-shaped pores (0.4–0.8 nm). chemistry analysis evidenced presence oxygenated groups (carboxylic, esters, phenolics). Activated indicated that concentrations leached did not exceed maximum permissible limit drinking Phenol an exothermic process capacity 272 mg/g 10 °C. Finally, it confirmed diffusion drastically affected hindered phenomena due similarity molecular size average micropores, result effective coefficient between 6.10 × 10?0 5.50 10?12 cm2/s tortuosity value 3.3 obtained.
