Degradation of Acetaminophen and Its Transformation Products in Aqueous Solutions by Using an Electrochemical Oxidation Cell with Stainless Steel Electrodes

Abstract: Abstract:In this study, a novel electrochemical oxidation cell using stainless steel electrodes was found to be effective in oxidizing acetaminophen and its transformation products in short reaction times. Aqueous solutions of 10 mg/L-acetaminophen were prepared at pH 3, 5, 7, and 9. These solutions were electrochemically treated at direct current (DC) densities of 5.7 mA/cm 2 , 7.6 mA/cm 2 , and 9.5 mA/cm 2 . The pharmaceutical and its intermediates/oxidation products were determined by using high pressure li… Show more

“…Detection of photodegradation by-products by HPLC: The most efficient paracetamol photodegradation reaction was identified using a high-pressure liquid chromatograph (Agilent 1200-Santa Clara, CA, USA) with a C18 reversed-phase column. The chromatographic conditions were similar to those reported by López et al [33,34]. However, they were optimized for paracetamol and its by-products by using a mobile phase of methanol and acetic acid in 1% water with a v/v ratio of 40/60.…”

“…The solution pH was adjusted from 6.8 to 3.0 by adding HCl. The adjustment of pH was conducted to run the experiments under the optimum oxidation conditions obtained by López Zavala and Espinoza Estrada ( 2016 ) for synthetic solutions (pH 3). Then, the solutions were treated electrochemically at DC densities of 5.7 mA/cm 2 6 V) and 7.6 mA/cm 2 (12 V) and reaction times 1, 2.5, 5, 7.5, 10, 15, 20, 25, 30, 35, 40, 50, 60, 120, 240, 360, and 540 min.…”
