Optimization Of Heterogeneous Fenton And Photo Fenton Reactions For The Treatment Of Palm Oil Mill Effluent Using Response Surface Methodology

Disposal of untreated palm oil mill effluent (POME) has adverse effects on aquatic biota and the environment due to its high chemical oxygen demand (COD) and total organic carbon (TOC) content. This work investigated the effectiveness of magnetite nanoparticles (Fe3O4 NPs) and carbon-encapsulated ma...
