Avaliação do tratamento do poluente emergente 17α- Etinilestradiol, utilizando Persulfato de Sódio ativado por Diatomita modificada

Abstract

Emerging pollutants have been the subject of a worldwide study because they present a potential threat to the environment and human health, as a result of their continuous entry into the environment. In this context, researches are being developed with the aim of improving the methods for elimination or reduction of these. Through the Advanced Oxidative Process (AOP) radicals are generated in quantities sufficient to oxidize the chemicals present in effluents. Persulfate is a relatively new form of oxidant that has been investigated because of its high oxidation potential and by the fact it remains for longer in the medium. Based on this aspect, this work focuses on the treatment of the synthetic hormone 17α-ethinylestradiol (EE2) in aqueous systems, using traditional methods: activating the oxidant through pH, temperature and Metal (Iron) compared to the innovative method that will activate the Persulfate through the catalyst (Modified Diatomite). From the obtained 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, this pollutant does not yet have an agreement with a regulation of limits of intervention.
