‎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 TiO۲/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 (۵۰, ۱۰۰, ۱۵۰, and ۲۰۰ mg/L), pH of solution (۵, ۷, and ۹), photocatalyst dosage (۱-۴ g/L), and pH ۵, ۷, and ۹ were investigated. It is repeated three times for every single part of the experiment. The results show that the maximum degradation of ۷۱.۹% was achieved in acidic pH ۵, and the optimum concentration of photocatalyst was achieved at ۲ g/L, at an initial concentration of phenol equal to ۵۰ mg/L. Investigation of results in terms of thermodynamic aspects revealed phenol concentration۱۰۰ mg/L, pH =۵, and photocatalyst dose ۲ g/L were the first-order kinetic constant was achieved ۰.۰۰۵ min-۱ with R۲=۰.۹۴۲۷. In conclusion, using photocatalyst wastewater treatment is beneficial for organic pollution.
