Abstract Porous Fe-oxalate complexes were prepared by thermally treating iron sources and rice husks under nitrogen gas purging. Fe oxidation states of 0, 2.5+, and 3+ in the complex were identified by X-ray photoelectron spectroscopy, which were oxidized into ferrites and separated by the magnet after removal of methyl orange. The Fe-oxalate complex treated at 700 °C exhibited the strongest magnetic properties, and its catalytic ability to remove 100 ppm of methyl orange was optimized after 60 min. In conclusion, the oxalate ions in Fe-oxalate complex could promote the decomposition of organic compounds accelerating the OH radical generation in a UV Fenton-like system.
