dc.description.abstractMicropollutants are substances that are continuously released to environments and can present adverse effects to the environment, even when present at very low concentrations (trace levels). Among these compounds are the estrogens pharmaceutical drugs, since traditional sewage and drinking water treatment plants are not able to remove or degrade them1,2. Thus, new and more efficient treatments are required, such advanced oxidation processes or adsorption. Activated carbons (ACs) are known as low-cost carbonaceous materials used for removal of pollutants using adsorption processes3,4. This work aims to produce ACs from olive stone and to evaluate the simultaneous removal of four different estrogens by adsorption with the produced materials. From the olive stone by product generated in the olive oil extraction, five different materials were produced, namely (i) powdered olive stone, (ii) physical activated at 800°C (iii) carbonized at 500°C, (iv) chemical activated using phosphoric acid and (v) chemical activated with sodium hydroxide. The carbonization yield was calculated and the pH at point of zero charge (pHPZC) of the carbonaceous materials determined. The simultaneous quantification of estriol, estrone, 17 -estradiol and 17 - ethinylestradiol in aqueous solution was performed by high performance liquid chromatography with diode array detector (HPLC-DAD). The highest carbonization yield (57.5%) was observed using acid activation. The adsorbents production method also influences the pHPZC of the adsorbents, being more expressive by the acid activation with the lowest pHPZC (3.84). The olive stone raw-material shows an important potential to be used on the production of activated carbons with high carbonization yieldspt_PT
