Abstract
The effects of significant operational parameters such as initial pH, oxidant concentration and catalyst amount were investigated and optimized for a better removal of 3-MI at initial concentration of 20 mg Lâ1. Besides, the catalyst stability was evaluated according to the iron leached into the aqueous solution. Results revealed that the parameters affecting Fenton catalysis must be carefully chosen to avoid excessive iron release. Under optimized conditions, the magnetic catalyst exhibited a good catalytic performance. Total removal of 3 methyl indole and a remarkable organic mineralization, without significant leaching of iron, were attained within 120 min at pH 3.0 by using 0.4 g Lâ1 of Fe-MABs and 9.8 mmol Lâ1 of H2O2. The novel magnetic catalyst would be of potential application due to its high efficiency, easy recovery and good structural stability.
