Introduction: Xylene is an organic compound that is volatile and widely used in various industries, which is not only for the environment but also for human health even in low-risk concentrations. Today, among the methods for removing pollutants, photocatalytic removal methods Special attention is paid. The present study aimed to determine the efficiency of removal of xylene vapor from airflow using photocatalytic property of titanium dioxide on ZSM-5 zeolite.

Methods: In this experimental study, the characteristics of the catalysts were determined using BET, X-ray diffraction (XRD) and scanning electron microscopy scanning (FESEM). Xylene vapors were produced using a dynamical condenser system and the efficiency of xylene vapor depletion was investigated using UV / ZSM-5 / TiO2.

Results: Images and spectra obtained from XRD, EDS and FESEM tests showed that stabilization was well done. By increasing the concentration from 50 ppm to 150 ppm and increasing the flow rate from 0.3 to 0.5, the removal efficiency decreased and the removal efficiency at concentrations of 50, 100 and 150 was respectively 35.46, 22.70 And 17.37  percent.

Conclusion: The results showed that the use of composite substrates increases the efficiency of photocatalytic removal, and it is suggested that these adsorption and photocatalytic combination systems be used to remove other volatile organic compounds in the gas phase.
