Magnetic TiO2/Fe3O4-Chitosan Beads: A Highly Efficient and Reusable Catalyst for Photo-Electro-Fenton Process

Heterogeneous photo-electro-Fenton process is an attractive technology for the removal of recalcitrant pollutants. To better exploit presence irradiation source, a bifunctional catalyst with TiO2 nanoparticles embedded into iron–chitosan matrix was developed. The catalytic activity improved by optimization loaded content. prepared composite catalysts based on TiO2, Fe3O4 and chitosan were called TiO2/Fe3O4-CS beads. best optimal ratio TiO2/Fe = 2 exhibited high efficiency in degradation mineralization chlordimeform (CDM) insecticide. Under optimum conditions (concentration equal to 1 g L−1 applied current intensity 70 mA), real effluent doped 30 mg CDM efficiently treated, leading 80.8 ± 1.9% TOC reduction after 6 h treatment, total only h.The generated carboxylic acids minerals identified quantified. Furthermore, stability reusability developed examined, insignificant noticed four consecutive cycles process. Analyses using SEM, XRD VSM showed good physicochemical properties use.
