bone char was studied. Batch kinetics studies showed that a rapid uptake occurred during
the first 5min and was followed with a very slow intraparticle diffusion process. The sorption
kinetics was ideally conformed to pseudo-second equation, indicating several mechanisms
involved in the adsorption process. Equilibrium sorption isotherm studies showed that the
Freundlich isotherm model satisfactorily described the sorption data. The presence of co …
