ABSTRACT
-1 of MIP, which gave removal efficiency of above 91%. After 60 min, the change of adsorption capacities for 17-estradiol did not show notable effects. The Langmuir and Freundlich adsorption models were also applied to describe the equilibrium isotherms. Equilibrium adsorption data showed that the adsorption of 17 -estradiol onto the MIP fitted well to the Langmuir equation. The MIPs were easily regenerated after each experiment with Methanol:Acetic acid (4:1 v/v) solvent and reused.]]>
