Emerging pollutants have been subject of a worldwide study because they present a potential threat to the environment and human health, because of their continuous entry into the environment. In this context, researches are being developed with the aim of improving the methods for these pollutants elimination or reduction. Through the Advanced Oxidative Process (AOP) radicals are generated to oxidize the chemicals present in effluents. Thus, this work focuses on the treatment of the synthetic hormone 17α-ethinylestradiol in aqueous systems, using traditional methods: activating the oxidant through pH, temperature and iron ions compared to the innovative method that activated the persulfate by the catalyst (Modified Diatomite). According to the results, it can be concluded that the innovative activation method, using modified diatomite, was more efficient than the traditional methods, achieving a 98% removal of EE2 in 90 minutes of reaction.
