Background: Benzene, toluene, ethyl benzene and xylene compounds (BTEX) are very dangerous in terms of health and environmental and have high toxicity in aquatic environment. The purpose of this study was to investigate the performance analysis of Petroleum Hydrocarbons Xylene Using Solar Radiation UV/TiO2 Method in industrial synthetic waste. Methods: An experimental-interventional study was conducted in the laboratory scale. The reactor used was consisted of five connected glass modules with 3cm diameter and a drive motor for receiving maximum solar UV radiation. To determine the factors influencing the efficiency, elimination of the response signal to the noise ratio was calculated using the equation: Findings: Based on the findings obtained, the input xylene concentration had the most affect on the removal efficiency and the subsequent effective factors were respectively pH with the value of 7, the time in the range of 60 to 180 minutes and TiO2 concentration of 0.01 mol/l. Intensity of solar ray and temperature were in the range of 45 to 60 w/cm2 and 40 to 60 °C, respectively. Conclusion: The statistical Taguchi model showed significant relationship between the removal efficiency of xylene and the tested factors, and P < 0.1 was obtained in all the cases. Xylene concentration had the most effect on degradation performance. The removal efficiency increases by increasing xylene density. 93.33% of considered pollutant was removed in the optimum condition.
