ABSTRACT

The adsorption of phenol with the crosslinked polymer of P(MMA-MAh)-PEG₃₃ was studied. Through the research, it was found the adsorption was favored in acidic aqueous solution and almost needed 35 h to reach the equilibrium. The calculated thermodynamic parameters suggested that the adsorption of phenol onto P(MMA-MAh)-PEG₃₃ was spontaneous and exothermic in nature. From the kinetic research, the adsorption of phenol with the crosslinked polymer belonged to the first-order reaction. The adsorption isotherms of phenol with polymer well accorded with the Freundlich model.
