In this study, kinetic and equilibrium adsorption of a typical odorous compound, 2-methylisoborneol (2-MIB) onto PACs was studied. Three different types of commercially available PACs were used for the adsorption experiments. Raw water of Feng-Shen Waterworks (FSW) was chosen for the representative source water. The equivalent background compound (EBC) model was combined with the Freundlich isotherm to describe the equilibrium of 2-MIB on PAC in the raw water, while the homogeneous surface diffusion model (HSDM) was employed to simulate the adsorption kinetics. The models followed the experimental kinetic data very well, and equilibrium and kinetic parameters were extracted. Based on the extracted parameters, the models were able to predict the adsorption kinetic curves at different 2-MIB concentrations under different PAC dosages.
