Resumo(s)
Estrogens belong to the class of water micropollutants named as endocrine disrupting chemicals and are considered persistent substances in the environment. Estrogens are a type of hormones that are continuously released to environment presenting several undesirable effects on aquatic species and human health even when present at very low concentrations (trace levels) . Additionally, it is known that traditional sewage and drinking water treatment plants are not able to remove or degrade these compounds and additional treatments are required. Activated carbons (ACs) are low-cost carbonaceous materials with a high surface area. ACs undergo an activation process in order to increase its adsorption performance. Activation can be performed by physical treatment, in which the organic material is thermal treated with an atmosphere of air, CO2, and water vapor, or also by applying some chemical treatments using generally, strong acids, chloride salts or strong bases. With this work, we present an extensive set of experimental results that shows the valorization of olive stones residues to prepare activated carbons to be used as adsorbent for the removal of estrone (E1), 17β-estradiol (E2) and 17α-ethinylestradiol (EE2) by adsorption from water.
