dc.description.abstractCefdinir adsorption onto non-activated biochar (WL-BC) and activated biochars (WL-BC-H, WL-BC-OH) prepared from waste biomass (WL) is comparatively investigated in view of adsorption factors, adsorption isotherms and adsorption kinetics. Batch experiments are conducted to assess the effects of pH, adsorption time and initial antibiotic concentration. Various advanced techniques are applied to characterize the prepared biochars (BCs). Characterization of the new BCs reveal that the activation process do not have a significant effect on the chemical structure of activated carbons, but it increases the surface area up to eight times. The equilibrium data are simulated with the Langmuir adsorption model indicating monolayer adsorption for both activated biochars WL-BC and WL-BC-H. However, the adsorption isotherm for WL-BC-OH is represented well by the Freundlich model, which shows that multilayer adsorption took place. The kinetic data are analyzed using various kinetic models. The maximum adsorption capacity of the activated biochar is approximately tenfold in comparison to the non-activated biochar. Additionally, the real wastewater experiments with treated campus wastewater show that the adsorptive performance of the activated biochar is not affected by other ions. Consequently, BCs derived from defatted laurel leaves could be effective and eco-friendly adsorbents for removing cefdinir from wastewater.
