Heterogeneous Fenton Degradation Of Ofloxacin In Aqueous Solution Using Fe3O4-Zeolite, Fe3O4-Montmorillonite And Fe3O4-Montmorillonite Alginate Composites

The primary aim of this study is to develop an economical, stable and effective heterogeneous catalyst for wastewater remediation via the Fenton oxidation process. Fe3O4 can effectively activate H2O2 to produce hydroxyl radicals, but the particles agglomerate easily. To solve this problem, Fe3O4-zeo...
