Resumo: This study evaluated the degradation potential of the drug Sertraline by means of photocatalysis processes, with the combination of ultraviolet (UV) energy and different semiconductors. Photocatalytic assays were performed in 10 mL of Sertraline solutions containing 10 mg L-1, added to the different semiconductors (10 mg). The samples were submitted to radiation (UV) in five degradation times (0, 5, 10, 30, 60 and 120 minutes). The determination of Sertraline concentration was by high performance liquid chromatography with UV detection. (HPLC-UV). Sertraline degradations of 51%, 74%, 75% and 83% were determined after application of photolysis, photocatalysis TiO2, TiO2-Mn and TiO2-B, respectively. Thus, the higher efficiency in the degradation process was determined for the boron-doped TiO2 semiconductor. Thus, the application of the photocatalysis process can be of great importance in the effluent treatment processes, and the insertion of doping agents can make semiconductors more active in photocatalysis processes.

Ensaios fotocatalíticos foram realizados em 10 mL de soluções de Sertralina com concentrações 10 mgL-1, adicionados dos diferentes semicondutores (10 mg). As amostras foram submetidas a radiação (UV) em cinco tempos de degradação (0, 5, 10, 30, 60 e 120 minutos). A determinação da concentração da Sertralina foi por cromatografia líquida de alta eficiência com detecção UV (CLAE-UV). Degradações de Sertralina de 51%, 74%, 75% e 83% foram determinadas após aplicação da fotólise, fotocatalise TiO2, TiO2-Mn e TiO2-B, respectivamente. Assim, a maior eficiência no processo de degradação, foi determinado para o semicondutor de TiO2 dopado com Boro. Deste modo, a aplicação do processo de fotocatálise pode ser de grande importância nos processos de tratamento de efluentes e, a inserção de agentes dopantes pode tornar os semicondutores mais ativos em processos de fotocatálise.Universidade Federal de Campina Grande - UFCG2019-01-02info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://revistas.ufcg.edu.br/ActaBra/index.php/actabra/article/view/11710.22571/2526-4338117Acta Brasiliensis; Vol 3 No 1 (2019): Acta Brasiliensis; 17-20Acta Brasiliensis; Vol 3 No 1 (2019): Acta Brasiliensis; 17-20Acta Brasiliensis; Vol 3 No 1 (2019): Acta Brasiliensis; 17-202526-43382526-432Xreponame:Acta Brasiliensis (Online)instname:Universidade Federal de Campina Grande (UFCG)instacron:UFCGporhttp://revistas.ufcg.edu.br/ActaBra/index.php/actabra/article/view/117/57Maldi, Caroline PizaMoreira, Ailton JoseFreschi, Gian Paulo Giovanniinfo:eu-repo/semantics/openAccess2021-07-12T20:04:01Zoai:ActaBra.revistas.ufcg.edu.br:article/117Revistahttp://revistas.ufcg.edu.br/ActaBraPUBhttp://revistas.ufcg.edu.br/ActaBra/index.php/actabra/oaiactabrasiliensis@gmail.com || actabrasiliensis@gmail.com2526-432X2526-4338opendoar:2021-07-12T20:04:01Acta Brasiliensis (Online) - Universidade Federal de Campina Grande (UFCG)false
