- •
Efficient and stable LaFeO3 catalyst is prepared by a simple sol-gel method.
- •
Ultrasound mediated Fe3+/persulfate Fenton-like system is developed.
- •
The key rate determining factors for the sonocatalytic degradation are evaluated.
- •
Synergism is obtained with Fe3+/ultrasound and persulfate/ultrasound systems.
- •
Heterogeneous perovskite type LaFeO3 catalyst is extremely recyclable.
