Abstract
This work reports the semiconductor assisted photochemical degradation of reactive azo dye such as congo red (CR) on combustion synthesized ferric oxide as a photo-catalyst. Ferric oxide was characterized by powder XRD, BET surface area, reflectance spectroscopy and powder density. BET surface area was found to be 3.4386 m 2 gm-1and has a particle size equals to 29.33 nm. Energy gap was found to be 2.12 eV by reflectance spectroscopy. 79 % COD removal was observed at pH 6 within 60 min. time duration using UV light (254 nm wavelength) as a source of radiation.
