‘An investigation into the occurrence and removal of pharmaceuticals in Colombian wastewater’
Botero-Coy, Ana Maria; Martínez-Pachón, Diana; Boix Sales, Clara; Rincón, Rolando J.; Castillo, Nancy I.; Arias Marín, L.P.; Manrique Losada, L.; Torres-Palma, Ricardo A.; Moncayo-Lasso, Alejandro; Hernandez, Felix Elsevier (2018)In this work, the presence of 20 pharmaceuticals in wastewater from Colombia is investigated. Several widely consumed compounds have been detected in wastewater samples from different origins and geographical areas in ... -
Comparative degradation of two highly consumed antihypertensives in water by sonochemical process. Determination of the reaction zone, primary degradation products and theoretical calculations on the oxidative process
Serna-Galvis, Efraim A.; Isaza-Pineda, Laura; Moncayo-Lasso, Alejandro; Hernandez, Felix; Ibáñez, Maria; Torres-Palma, Ricardo A. Elsevier (2019)This work compares the sonochemical degradation of losartan and valsartan (antihypertensives) in water. Initially, the suitable operational conditions of ultrasonic power density and frequency were established. Under such ... -
Degradation of seventeen contaminants of emerging concern in municipal wastewater effluents by sonochemical advanced oxidation processes
Serna-Galvis, Efraim A.; Botero-Coy, Ana Maria; Martínez-Pachón, Diana; Moncayo-Lasso, Alejandro; Ibáñez, Maria; Hernandez, Felix; Torres-Palma, Ricardo A. Elsevier (2019)The simultaneous degradation of seventeen emerging concern pollutants in effluent from the municipal wastewater treatment plant (MWTP) of Bogotá-Colombia was studied using high frequency ultrasound (375 kHz). The considered ... -
Effective elimination of fifteen relevant pharmaceuticals in hospital wastewater from Colombia by combination of a biological system with a sonochemical process
Serna-Galvis, Efraim A.; Silva-Agredo, Javier; Botero-Coy, Ana Maria; Moncayo-Lasso, Alejandro; Hernandez, Felix; Torres-Palma, Ricardo A. Elsevier (2019)This work presents the treatment of selected emerging concern pharmaceuticals in real hospital wastewater (HWW) from Tumaco-Colombia by combination of a biological system with a sonochemical process. Fifteen compounds, ... -
Elimination of contaminants of emerging concern and their environmental risk in world-real municipal wastewaters by electrochemical advanced oxidation processes
Martínez-Pachón, Diana; Botero-Coy, Ana Maria; Hernandez, Felix; León López, Nubia; Torres-Palma, Ricardo A.; Moncayo-Lasso, Alejandro Elsevier (2022-05-09)In this study, sixteen contaminants of emerging concern (CECs), present in the effluent of the wastewater treatment plant (WWTP) “Salitre” (Bogotá – Colombia), were subjected to several electrochemical advanced oxidation ... -
LC-QTOF MS screening of more than 1,000 licit and illicit drugs and their metabolites in wastewater and surface waters from the area of Bogotá, Colombia
Hernandez, Felix; Ibáñez, Maria; Botero-Coy, Ana Maria; Bade, Richard; Bustos López, Martha Cristina; Rincón, Javier; Moncayo-Lasso, Alejandro; Bijlsma, Lubertus Springer (2015-08)A large screening of around 1,000 emerging contaminants, focused on licit and illicit drugs and their metabolites, has been made in urban wastewaters (both influent and effluent) and surface waters from the area of Bogotá, ... -
Optimization and application of a continuous flow photo-electro-Fenton system for the removal of pharmaceutical active compounds detected in irrigation water of Bogotá – Savanna (Colombia) Crops
Delgado-Vargas, Carlos A.; Barreneche Vasquez, Johan Sebastian; González Cógua, Natalia; Botero-Coy, Ana Maria; Hernandez, Felix; Martínez-Pachón, Diana; Moncayo-Lasso, Alejandro Elsevier (2023)In this study, a continuous flow photo-electro-Fenton (PEF) system was evaluated for its ability to remove pharmaceutically active compounds (PhACs) from irrigation water used in Bogotá-savanna crops. The PEF system consisted ... -
Photo-electro-Fenton process applied to the degradation of valsartan: Effect of parameters, identification of degradation routes and mineralization in combination with a biological system
Martínez-Pachón, Diana; Ibáñez, Maria; Hernandez, Felix; Torres-Palma, Ricardo A.; Moncayo-Lasso, Alejandro Elsevier (2018-12)In this work, the oxidation of the antihypertensive drug valsartan by the Electro-Fenton (EF) and photo-electro-Fenton (PEF) processes was studied using a Ti/IrO2 doped with SnO2 as anode, and a carbon felt air diffusion ... -
Treatment of two sartan antihypertensives in water by photo-electro-Fenton using BDD anodes: Degradation kinetics, theoretical analyses, primary transformations and matrix effects
Martínez-Pachón, Diana; Serna-Galvis, Efraim A.; Ibáñez, Maria; Hernandez, Felix; Ávila-Torres, Yenny; Torres-Palma, Ricardo A.; Moncayo-Lasso, Alejandro Elsevier (2021-05)Degradation of two representative antihypertensives, losartan (LOS) and valsartan (VAL) in water by photo-electro-Fenton (PEF), using a BDD anode in presence of sulfate anion was evaluated.
