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 ... -
