A novel hybrid mesostructured silica for the solid-phase extraction of estrogenic hormones from waters

Mesoporous silica functionalized with octadecyl groups (denoted as SBA-15-C18) was prepared and characterized. The adsorption capacity of the prepared SBA-15-C18 for a mixture of twelve endocrine disrupting compounds (synthetic and natural estrogenic hormones) in aqueous media was evaluated by off-l...
