Ibuprofen oxidative degradation in the presence of Fenton-catalyst based on MgFe 2 O 4 nanoparticles

Catalytic properties of MgFe 2 O 4 nanoparticles during oxidative destruction of non-steroidal anti-inflammatory drug ibuprofen were studied. The influence of the conditions of the catalytic process on the efficiency of ibuprofen decomposition was established. It was shown that at the catalyst content of 0.5 g/L, H 2 O 2 concentration of 20.0 mmol/L and pH of 6.0 for 40 min, a decrease in the ibuprofen concentration from 10.0 mg/L to less than detected limit is achieved. It was found that in the process of catalytic destruction the degree of ibuprofen mineralization reached 100 %. The conducted research shows the prospects of practical application of the developed Fenton-like heterogeneous catalyst for wastewater treatment from pharmaceutically active compounds.
