Background and purpose: Dyes and cyanide are the most important sources of environmental pollution, found in industrial wastewater, which are harmful for human health and environment. The purpose of this research was to investigate the Kinetic and efficiency of titanium dioxide photacatalytic process in removal of Reactive Black 5 (RB5) dye and cyanide from aquatic solution in a batch system.
Materials and methods: This research was an applied-fundamental study. Â reactor was designed and optimum dosage of TiÔ2 was determined, 1g/L keeping other parameters constant. The effect of pH, contact time and initial Reactive Black 5 )RB5) dye and cyanide concentration was studied at a constant concentration of TiÔ2 (1 g/L).
Results: The result showed that removal efficiency of Reactive Black 5 )RB5) dye and cyanide decreased with increasing pH and initial Reactive Black 5 )RB5) dye and cyanide concentration. There was also an increase in specific removal efficiency by increasing the contact time and the TiÔ2 dosage. Ïn addition, kinetic parameters were obtained by application of Langmuir and Hinshelwood equation.
Çonclusion: The results showed that removal of Reactive Black 5 )RB5) dye and cyanide can be efficiently performed by ÜV/TiÔ2
