Decomposição dos Antirretrovirais Lamivudina e Zidovudina pelo Processo Fotofenton Assistido no Efluente de Indústria Farmoquímica

Abstract: Os princípios ativos utilizados na formulação de medicamentos compõem os contaminantes presentes na estação de tratamento de indústria farmacêutica. Visando alternativas que levem a soluções eficazes, os processos oxidativos avançados (POA) têm atraído grande interesse da comunidade científica e industrial. Foram realizadas degradações dos antirretrovirais (lamivudina -3TC e zidovudina -AZT), por oxidação, fotodegradação e foto-oxidação, presentes em efluentes de uma indústria farmoquímica do Estado de Goiás. … Show more

“…Darunavir, lamivudine, and tenofovir have NOEC values below 10 mg/L, which are possible concentrations in a pharmaceutical effluent. Regarding concentration in industrial effluents, the work by Souza et al (2010) shows that the maximum concentrations of zidovudine and lamivudine, which are 6.29 mg/L and 3.22 mg/L respectively, do not come close to the NOECs for these substances.…”

“…High concentrations are expected in industrial effluent treatment plants. A study with real effluents from a zidovudine and lamivudine production plant found drug concentrations of 6.29 mg/L and 3.22 mg/L, respectively (Souza, et al, 2010). Therefore, even if a drug is classified as highly toxic and by the studies currently published, there is an indication that the values of environmental concentrations are low.…”

“…A eficiência do processo Fenton depende de alguns parâmetros operacionais: pH, concentrações de H2O2, Fe 2+ e do contaminante, temperatura, composição da matriz (presença de ânions -carbonato/bicarbonato, fosfato, cloreto, sulfato, etc), fonte de radiação e espécie de ferro (SOUZA et al, 2010;BRITO e SILVA, 2012;TROVÓ et al, 2013).…”
