Abstract

Herein, Fe₃O₄@MOF-2 (MOF: metal-organic framework) nanocomposite, as a heterogeneous nanocatalyst, was applied to activate persulfate (PS) in the attendance of ultrasonic (US) irradiation (Fe₃O₄@MOF-2/US/PS) for degradation of diazinon. The evaluation results showed that, in the acidic solution (pH = 3), the reaction rate constant of Fe₃O₄@MOF-2/US/PS system (0.0546 min⁻¹) was more than 6-folds than that of the US/PS system (0.0079 min⁻¹). Reducing the diazinon concentration, along with raising the Fe₃O₄@MOF-2 dosage and the US bath power favored the degradation of diazinon. It was found that Fe₃O₄@MOF-2 had fine catalytic performance and reuseibility. The diazinon decomposition pathway was proposed by GC–MS analysis.
