Factors Affecting Fenton Oxidation of Acetaminophen in a Fluidized-Bed Reactor
Publication: Journal of Environmental Engineering
Volume 140, Issue 1
Abstract
Acetaminophen (ACT), an over-the-counter analgesic and antipyretic, remains one of the most frequently used household medications. This drug persists in domestic effluents in significant concentrations even after conventional treatment. This study demonstrates the effectiveness of fluidized-bed Fenton process to decompose acetaminophen in synthetic wastewater. Parametric studies were conducted to evaluate the effects of initial pH, initial ACT concentration, and dosages on ACT oxidation. At optimum operating parameters, up to 97.83% ACT degradation was attained after 2 h of reaction. For interference studies of organic acids (oxalic, fumaric, maleic, acetic, succinic, malonic, and formic acids), oxalic acid was found to limit ACT degradation to only 9.26%.
