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 acidicsolution (pH = 3), the reaction rate constant of Fe3O4@MOF-2/US/PS system (0.0546 min 1) was morethan 6-folds than that of the US/PS system (0.0079 min 1). Reducing the diazinon concentration, alongwith raising the Fe3O4@MOF-2 dosage and the US bath power favored the degradation of diazinon. It wasfound that Fe3O4@MOF-2 hadfine catalytic performance and reuseibility. The diazinon decompositionpathway was proposed by GC–MS analysis.
