Aplicação de Nanopartículas de Fe° Estabilizadas com Sba-15 Para Remediação de Água Contaminada com Metronidazol
Palavras-chave:
Anopartículas de fe°. Remoção. Metronidazol. sba-15.
Resumo
Uma grande quantidade de medicamentos é consumida anualmente, o que vem gerando uma grande preocupação com relação à contaminação ambiental, especificamente a contaminação de efluentes. Dentre os fármacos mais utilizado, destaca-se os antibióticos. O composto Metronidazol (MNZ) tem sido alvo de estudos. Os estudos realizados comprovaram a eficiência das NPs na remoção do MNZ, de acordo com os parâmetros avaliados e estabelecidos – pH, massa de nFZV/SBA-15 e concentração do fármaco. Processo de tratamento redutor alternativo utilizando NPs contendo Fe é muito promissor para a eliminação de fármacos.
