Factors Affecting Fenton Oxidation of Acetaminophen in a Fluidized-Bed Reactor
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%.- 1 January 2014

Optimization of acetaminophen degradation by fluidized-bed Fenton process
Recalcitrant compounds in pharmaceutical wastewaters render biological treatment inadequate. Conventional Fenton technology, though a promising alternative, suffers from high sludge generation. In this study, fluidized-bed (FB) Fenton process, an improvement of traditional Fenton method, was used to decompose acetaminophen (ACT) from aqueous solutions. Optimization of important parameters: initial pH, ferrous ion and hydrogen peroxide dosages, was carried out using Box–Behnken Design (BBD). Effects of all factors and their interactions on ACT decomposition were significant. At optimum operating conditions, ACT degradation reached 97.8% while iron removal of 62.92% was achieved. In addition, the high hydrogen peroxide efficiencies of FB-Fenton process with respect to ACT degradation and COD removal make this technology a cost-effective option in treating acetaminophen-contaminated wastewaters.
