Among different methods for produced water treatment, photocatalytic process is an alternative and innovative technology that is more used in water treatment. In this work BTEX was used as an indicator of produced water. γ-Fe2O3 nanoparticles have been synthesized via co-precipitation methods. XRD, DRS, FTIR and SEM techniques have been employed for detecting the particle size, morphology, different functional groups, the optical absorption characteristics and the crystal structure of the synthesized nanoparticle. Experimental tests were designed by the OFAT method. The effective ranges of the main factors on the photocatalytic degradation of BTEX including pH (3–7), catalyst concentration (0–250 mg L−1), UV light intensity (0–100 W) and visible light intensity (0–225 W) were obtained. When maghemite nanoparticles are under visible light and UV light, the best removal efficiency achieved 95% in 5 days and 97% in 90 min, respectively. In addition the photocatalytic process, adsorption and photolysis process of maghemite nanoparticles were studied.
