Özet
Herein, N/O-doped activated carbon (ACON) was obtained through carbonization of acorn pulp followed by hydrothermal reaction with oxalic acid and urea. The synthesized activated carbon samples were employed as adsorbents for methylene blue (MB) adsorption. The admirable properties provided high MB adsorption efficiency (94.21 %), which was 1.63 times greater than that of the bare activated carbon (57.60 %). This could be due to the enhancement of specific surface area and the formation of new active groups, supporting BET, SEM, FTIR and XPS analyses. The adsorption of dye onto ACON was a spontaneous endothermic process, as well as the adsorption mechanism could be explained with the pseudo-second-order kinetic model and the Langmuir isotherm model. Adsorption efficiency decreased due to the competition of cationic species in different water matrices with MB. In the fourth cycle, 71.8 % MB removal was achieved, and the sorbent was found relatively stable. The interactions were proposed to mainly account for sufficient combination of cationic dye molecules and nearly amphoteric ACON surface. In addition, the adsorbent showed promising performance in malachite green (MG) and ciprofloxacin (CPx) adsorption processes. To conclude, this study showed the applicability of N/O-doped activated carbon in wastewater treatment systems.
