Artigo IPEN-doc 28903 Gas chromatography-mass spectrometry analysis of irradiated fluoxetine aqueous samples2021 - REDÍGOLO, MARCELO M.; CALVO, WILSON A.P.; BOIANI, NATHALIA F.; TOMINAGA, FLAVIO K.; BORRELY, SUELI I.The last decade witnessed the drastic increase in the use of antidepressant drugs, being fluoxetine the most prescribed worldwide. Conventional wastewater treatment is inefficient in removing fluoxetine and its accumulation in water bodies and water living organism is inevitable. Among several methods for contaminant removal from wastewater, electron beam irradiation is an efficient and green technology. This work presents the characterization of aqueous fluoxetine samples before and after irradiation. Gas chromatography coupled to mass spectrometry was used to identify the original compound and its irradiation products. Results indicate a drastic reduction in fluoxetine presence after the irradiation process. Radiolysis pathways were proposed based on mass fragments identification.Artigo IPEN-doc 28201 Degradation and toxicity of amoxicillin after electron beam irradiation2021 - VILLARDI, B.D.; REDÍGOLO, M.M.; TOMINAGA, F.K.; LEBRE, D.T.; BORRELY, S.I.Artigo IPEN-doc 25002 Preparación de muestras del médio ambiente para análisis por médio de técnicas cromatograficas2017 - VEGA, O.; LOPES, P.R.; AMARAL, P.O.; GONSCHOROWSKI, G.; OLIVEIRA, J.P.; FABBRO, R.; MESQUITA, K.A.; GIMENEZ, M.P.; REDIGOLO, M.Este artículo explora la ciencia de la preparación de muestras para matrices sólidas, líquidos y gases, utilizados en el laboratorio del Centro de Química y Medio Ambiente del IPEN. Extracción de neonicotinoides del agua por LLE (Liquid-Liquid Extraction), extracción de hidrocarburos aromáticos policíclicos (PAHs) del agua atraves de DLLME (Dispersive liquid - liquid micro extraction) y el uso de extracción en fase sólida SPE (Solid Phase Extraction) para el análisis de hormonas en agua son descritos. Limites de detección que utilizan estas técnicas son descritas en este trabajo.Artigo IPEN-doc 21573 Chemical characterization of persistent organic pollutants (POPs) and development of its decomposition in an industrial area of São Paulo, Brazil2015 - OLIVEIRA, J.P.R.; RIELLA, H.G.; LAINETTI, P.; REDIGOLO, M.M.; AMARAL, P.O.; MOURA, S.C.; BUSTILLOS, J.O.V.Artigo IPEN-doc 21134 PY-GC-MS applied to the identification of synthetic resins in brazilian painting2015 - REDIGOLO, MARCELO M.; AMARAL, PRISCILA O.; LEAO, CLAUDIO; CREPALDI, CAIKE; RUSSO, TATIANA; MENDONCA, VALERIA de; MUNITA, CASIMIRO S.; BUSTILLOS, OSCAR V.Artigo IPEN-doc 21099 Analysis of hydrogen, carbon, sulfur and volatile compounds in (Usub(3)Sisub(2)-Al) nuclear fuel2015 - MOURA, SERGIO C.; REDIGOLO, MARCELO M.; AMARAL, PRISCILA O.; LEAO, CLAUDIO; OLIVEIRA, GLAUCIA A.C. de; BUSTILLOS, OSCAR V.Artigo IPEN-doc 21063 Development of method for determination of sodium monochloroacetate and sodium dichloroacetate in cocoamido propyl betaine by gas chromatography: FID, ECD and MS2015 - LEAO, CLAUDIO; REDIGOLO, MARCELO M.; AMARAL, PRISCILA O.; BUSTILLOS, OSCAR V.Artigo IPEN-doc 20995 Analysis of neonicotinoids by gas chromatography coupled to nuclide sup(63)Ni - electron capture detector - GC/ECD2015 - AMARAL, PRISCILA O.; LEAO, CLAUDIO; REDIGOLO, MARCELO M.; CREPALDI, CAIKE; BUSTILLOS, OSCAR V.
