The presence of pharmaceuticals in water is a worldwide concern due to potential damage human and environmental health. For example, compounds such as the β-blocker atenolol (ATE), widely used for treatment cardiac disease, are detected drinking since conventional plants not designed remove them. Thus, evaluation ATE removal at different oxidative processes, identification its degradation products their toxicity necessary.Aqueous solutions (10 mg/L) were submitted treatments chlorination...
Miconazole-loaded nanoparticles coated with hyaluronic acid (miconazole-loaded nanoparticles/HA) were developed to overcome the limitations of conventional therapy vulvovaginal candidiasis (VVC). They synthesized by emulsification and solvent evaporation techniques, characterized diameter, polydispersity index, zeta potential, encapsulation efficiency, atomic force microscopy (AFM), evaluated in terms efficacy against C. albicans vitro, tested a murine VVC model. Nanoparticles showed 211nm...
Contaminants of emerging concern are organic compounds used in large quantities by the society for various purposes. They have shown biological activity at low concentrations, which gives great environmental relevance. The difficulty to detect and quantify contaminants environment stimulates development appropriate analytical methods. In this work a chemometric approach positive negative electrospray ionization (ESI) optimization simultaneous determination water samples liquid...
RESUMO Os compostos de preocupação emergente (contaminants of emerging concern - CECs) atingem constantemente os corpos d’água via lançamento esgoto sanitário, efluentes industriais e lixiviados aterro, disposição inadequada resíduos sólidos escoamento superficial, ocasionando a poluição dos cursos d’água. Geralmente estes se encontram em concentrações da ordem nanograma por litro ou micrograma litro, dificultando sua análise onerando esse processo, demandando, assim, o desenvolvimento...
RESUMO Fármacos e desreguladores endócrinos são encontrados em águas naturais brasileiras, incluindo alguns mananciais de abastecimento, também função da baixa cobertura coleta tratamento esgotos no Brasil. Nesse cenário, o presente trabalho intentou avaliar a remoção três fármacos - sulfametoxazol (SMX), diclofenaco (DCF) 17β-estradiol (E2) água destilada por meio oxidação com cloro (hipoclorito sódio), variando-se dose tempo contato ensaios batelada. As soluções cloradas foram analisadas,...
Miconazole-loaded nanoparticles coated with hyaluronic acid (miconazole-loaded nanoparticles/HA) were developed to overcome the limitations of conventional therapy recurrent vulvovaginal candidiasis (RVVC). They synthesized by emulsification and solvent evaporation techniques, characterized diameter, polydispersity index, zeta potential, encapsulation efficiency, in vitro drug release, atomic force microscopy (AFM), stability at 8 oC, evaluated terms cytotoxicity against keratinocyte cells...
Neste estudo foi avaliada a remoção de sulfametoxazol, diclofenaco e 17β-estradiol em água natural por meio da oxidação com cloro. As concentrações iniciais dos microcontaminantes, bem como o tempo após aplicação do cloro, apresentaram diferenças significativas na compostos interesse. águas naturais foram submetidas ao tratamento clarificação seguido pós-cloração, os resultados revelaram que melhor eficiência remoção, dosagem cloro 2,0 mg.L-1 ordem 58%, 54% 67% para diclofenaco,...
