Mesoporous silica, bi-functionalized with octadecyl and aminopropyl groups was prepared and characterized. The adsorption capacity of the prepared silica for a mixture of twelve endocrine disrupting compounds in water was evaluated by solid-phase extraction and compared with a commercial phase. Analytes were determined by high performance liquid chromatography. Under optimized conditions, the material showed recoveries near 100% with standard deviations between 3 and 10%, with exception of estriol and prednisolone which showed recoveries of 66 and 82%, respectively.
