Ethyl benzene is a volatile organic compound that is widely used in various industries. Ethyl benzene is a hazardous air pollutant not only for the environment but also for human health and hence there is a possibility of carcinogenesis in long-term exposure. Considering the fact that ethyl benzene is photo catalytic activity based in removal of VOCS vapors under visible light irradiation leading to serious health problems, the present study aimed to evaluate the gas-phase from airflow using photo catalytic property of titanium dioxide on 13X zeolite, in Ahvaz, Iran. In this experimental study, the characteristics of the catalysts were determined using BET method, X-ray diffraction (XRD), and scanning electron microscopy scanning (FESEM). Ethyl benzene vapors were produced using a dynamical condenser system and the efficiency of removal of ethyl benzene vapor depletion was investigated using 13X/UV and13X/UV/TiO2 (5 wt. %). The obtained results of the images and spectra from XRD, and FESEM showed good signs of immobilization. The findings revealed that the removal efficiency decreased by increasing the concentration from 25 ppm to 125 ppm and increasing the flow rate from 0.5 to 1.00. The removal efficiency at concentrations of 25, 75, and 125 was 57.8%, 37/2 %, and 24/64, respectively. The results showed that the use of substrates increased the efficiency of photo catalytic removal, by about 60%. It is therefore suggested that these adsorption and photo catalytic combination systems be used to remove other volatile organic compounds in the gas phase.
