The purpose of this study was to evaluate the adsorption capacity of endocrine disrupters (EDs), estriol (E3) and estrone (E1) in a mesoporous molecularly imprinted polymer (MMIP) and for comparison purposes in a mesoporous non-imprinted polymer (MNIP). These materials were characterized by the techniques of thermogravi-metric analysis, Brunauer-Emmett-Teller, infrared spectroscopy, scanning electron microscopy and surface wettability. To evaluate the adsorption process of EDs in the adsorbent materials the parameters: pH, contact time, concentration and temperature were optimized. After optimization, the materials showed adsorption for both EDs around 100 %. Experimental kinetic data were adjusted correctly by the pseudo-second order model for both MMIP and MNIP. The results of the isothermal studies showed better adjustments of the experimental data by the Langmuir model, showing for MMIP and MNIP 323.1 and 237.4 mg g(-1) for E3 and 371.2 and 285.3 mg g(-1) for E1, respectively. From the thermodynamic study, from the values of Delta H-(sic) and Delta G((sic)) it was possible to indicate that the adsorption process occurs in an endothermic and spontaneous manner during the study.
