The waste-derived adsorbents were prepared by a two-step process: chemical activation (with ZnCl2 and KOH) followed by pyrolysis. The mesoporous adsorbents were found to have BET surface area comparable to commercial activated carbon (surface area=495-515m2/g). The adsorption runs were performed in orbital shaker with synthetic phenolic wastewater (phenol concentration=50-250mg/L) to investigate the effect of various reaction parameters. The equilibrium phenol adsorption data could be described by Redlich-Peterson isotherm model and the pseudo first-order kinetic model exhibited the best fit to time-based adsorption data. The phenol adsorption was endothermic for all adsorbents. The performance of the thermally regenerated waste-derived adsorbents in the wastewater treatment was found to reduce significantly.
