where qe is the equilibrium adsorption capacity of polymeric adsor- bents (mgg−1), Ce is the equilibrium MTBE concentration in the aqueous solution (mg l−1 ), q∞ is the maximum adsorption capacity (mg g−1 ), and b is the isotherm parameter (l mg−1 ), respectively.
The adsorption of MTBE over the postcrosslinked polymer fol- lowed the linear adsorption isotherm:
