Photo-Oxidation of Organic Dye by Fe2O3 Nanoparticles: Catalyst, Electron Acceptor, and Polyurethane Membrane (PU-Fe2O3) Effects

The textile industry’s discharges have long been regarded as severe water pollution. photocatalytic degradation of dyes using semiconductors is one the crucial methods. present study efficiently used mechanical method to synthesize Iron oxide Nanoparticles. XRD, FT-IR, UV-Vis DRS, and Raman analyses were performed analyze structural optical. From data provided by XRD data, we believed that as-synthesized was pure hematite (α-Fe2O3) with a hexagonal structure. Additionally, EDS results show synthesized material pure. By adjusting specific parameters, including dye concentration, catalyst dosage, pH, oxidizing agent such H2O2 K2S2O8, eosin yellowish Fe2O3 photocatalyst has discussed. kinetics studied. A also conducted nanoparticles attached polyurethane polymer (PU) investigate its activity on methylene blue, methyl orange, indigo carmine. In 30 minutes, nearly 90% had degraded. total organic carbon (TOC) analysis confirmed this result.
