摘要: The imidacloprid was mineralized by heterogeneous photo-Fenton process in a three-phase
fluidized bed reactor using waste iron oxide as catalyst. The effects of catalyst loading, dosage of
H2O2 and pH were investigated to determine the optimal experiments conditions. The results
revealed that TOC removal efficiency increases with an increase in H2O2 dosage of up to
105.0 mM, an increase in catalyst dosage from 1.0 to 5.0 g L−1, and a decrease in pH from 5.0 to
3.5. Under the optimal conditions, 97.7% TOC removal was achieved in 6 h under 254-nm UV
irradiation. Moreover, recycling experiments indicated that the waste iron oxide had a good
stability and the TOC removal of pesticide yielded more than 80% under the fourth recycles.
