Description In the present study, stabilized landfill leachate treatment by heterogeneous Fenton and electro-Fenton
(EF) was carried out. Iron-manganese binary oxide loaded zeolite (IMZ) was used as a catalyst for
generating hydroxyl radicals in the acidic medium. Heterogeneous Fenton process was capable of
removing 88.6% COD from landfill leachate at the optimal conditions, while 87.5% COD removal was
observed at optimal EF treatment conditions. Biodegradability of landfill leachate was increased significantly from 0.03 to 0.52 after Fenton treatment. The prepared heterogeneous catalyst was found
reusable with a reduction in COD removal rate. Even though, both the processes are efficient for leachate
treatment, the low catalyst dosage requirement in case of EF process justifies that it is more feasible than
Fenton process.
