dc.description.abstract	The presence of pharmaceutical drugs, their metabolites and degradation products in the environment requires significant research and monitoring studies to assess the potential risks to human health and to the ecosystem. Due to the extremely low concentrations of these chemicals in the environment in the removal processes must be optimized in order to make them easier, quicker, less expensive, and more environmentally friendly than traditional techniques [1]. Many of these substances, including hormones, antidepressants, analgesics, antibiotics, and anti-inflammatories, among others, are heavily medical prescribed around the world to treat the most prevalent illnesses associated with modern society. Sertraline belongs to the pharmaceutical class of anti-depressant and is intensively used worldwide to treat severe cases of depression. According to recent studies, several active principles from this family of pharmaceutical drugs, despite being at very low levels of concentration in water, can have a variety of harmful side effects in the environment's flora and fauna in addition to the potential risk of underground water contamination later used for animal or even human consumption [2-4]. This work will present the main experimental results for the removal of sertraline from water by adsorption using activated carbon obtained from olive stones. The activated carbon material was obtained from olive stones, by powdering the granulated olive stones to a diameter of 0.25 mm, chemically activated with a strong acid and then carbonized. The equilibrium adsorption isotherms were obtained using the batch method and then fitted to different adsorption models, such as the Langmuir or Freundlich models for liquid phase adsorption. The most significant adsorption parameters were optimized, such as the solution pH, mass of the adsorbent used, adsorption contact time and adsorption temperature. The kinetics of the sertraline adsorption on the adsorbent was estimated using the pseudo-first and pseudo-second order models. Obtained results in this work clearly show that olive stones, usually a residue from the Portuguese and Mediterranean oliviculture, can be exploited as a promising and low-cost bio-mass source on the production of adsorbent materials with considerable potential to remove micropollutants, such as the antidepressant sertraline, from water	pt_PT
