Resumo: This work compared the efficiency of removing the 17-α-ethynylestradiol (EE2) through advanced oxidative processes (POA) and granular activated carbon adsorption (CAG). EE2 is a synthetic female hormone common in domestic sewage and effluent from pharmaceutical industries. This hormone is a type of emerging pollutant that causes endocrine disruption in living beings even in concentrations of nanograms order. The EE2 removal was analyzed in a prototype of a 10 L reactor, with upward flow CAG fluidized bed, using four lamps emitting ultraviolet radiation, with batch time of 2 hours in each process. Photolysis showed 5% of efficiency, while photocatalysis removed 87% of EE2. The adsorption processes in CAG and titanium dioxide immobilized at CAG removed 82 and 89%, respectively.

O EE2 é um hormônio feminino sintético comum no esgoto doméstico e no efluente de indústrias farmacêuticas. Esse hormônio é um tipo de poluente emergente que causa desregulação endócrina nos seres vivos mesmo em concentrações da ordem de nanogramas. Então foi analisada a remoção do EE2 em um protótipo de reator de 10 L, com leito fluidizado de CAG, de fluxo ascendente, utilizando quatro lâmpadas que emitem radiação ultravioleta, com tempo de batelada de 2 horas, cada processo. A fotólise apresentou 5% de eficiência, enquanto a fotocatálise removeu 87% de EE2, e os processos de adsorção em CAG e em dióxido de titânio imobilizado em CAG removera, 82 e 89%, respectivamente.Submitted by Franciele Moreira (francielemoreyra@gmail.com) on 2017-12-04T13:25:24Z No. of bitstreams: 2 Dissertação - Fernanda Lisboa Martins - 2017.pdf: 4877141 bytes, checksum: 9bbe680537dbf0bf672e46c97951bc77 (MD5) license_rdf: 0 bytes, checksum: d41d8cd98f00b204e9800998ecf8427e (MD5)Approved for entry into archive by Luciana Ferreira (lucgeral@gmail.com) on 2017-12-06T11:35:00Z (GMT) No. of bitstreams: 2 Dissertação - Fernanda Lisboa Martins - 2017.pdf: 4877141 bytes, checksum: 9bbe680537dbf0bf672e46c97951bc77 (MD5) license_rdf: 0 bytes, checksum: d41d8cd98f00b204e9800998ecf8427e (MD5)Made available in DSpace on 2017-12-06T11:35:00Z (GMT).
