In this work, the degradation kinetics of organic contaminants via Fenton reaction were studied. BPA was used as a model compound, and the Fenton reaction was induced by iron oxide nanoparticles under H2O2 and exposed to an alternating magnetic field (AMF) exposure. Iron oxide nanoparticles were synthesized by a co-precipitation method and were subjected to different characterization methods including DLS, FTIR, TGA and AMF heating. More specifically, the degradation of the model compound was studied under different conditions, such as pH, IONP/H2O2 ratio, BPA/H2O2 ratio). The Fenton reaction was enhanced by making use of hydroxylamine as a catalyst. The model compound degradation was determined to follow 2nd order kinetics and achieved a 57% degradation after 30 min. Optimum conditions for this degradation were determined to be at pH 3, 20 mM hydrogen peroxide and 6 mM of hydroxylamine. However, there was no significant difference between the degradation of the model compound under AMF exposure and water bath at 37 °C. These results suggested illustrate the potential application of iron oxide nanoparticles in organic contaminant degradation through Fenton process under AMF exposure.
