Affecting Parameters on Photocatalytic Degradation of Organic Contaminants in a Synthesized Wastewater Utilizing Concentrated Solar UV

In the present research, the removal of phenol from synthesized wastewater by TiO2/UV has been investigated. An originality of this study is its use of UV solar in Mahshar, an area in the south of Iran, and obtaining experimental data. The effect of parameters is included phenol initial concentration (50, 100, 150, and 200 mg/L), pH of solution (5, 7, and 9), photocatalyst dosage (1-4 g/L), and pH 5, 7, and 9 were investigated. It is repeated three times for every single part of the experiment. The results show that the maximum degradation of 71.9% was achieved in acidic pH 5, and the optimum concentration of photocatalyst was achieved at 2 g/L, at an initial concentration of phenol equal to 50 mg/L. Investigation of results in terms of thermodynamic aspects revealed phenol concentration100 mg/L, pH =5, and photocatalyst dose 2 g/L were the first-order kinetic constant was achieved 0.005 min-1 with R2=0.9427. In conclusion, using photocatalyst wastewater treatment is beneficial for organic pollution.
