Abstract

The degradation of 4-CHLORO-NITROBENZENE (CNB) in aqueous solution by sonolysis, by photocatalytic, and by combination of both was investigated in laboratory-scale experiments. The experiments was conducted with a sonicator ( UP 400S ) operated at 24 KHz and 400 W ULTRASONIC power. The temperature solution was kept constant at 30oC and pH was controlled at 2,6,8 and 10. The TiO2 nanoparticles (Rutile and Anatase) were used as a catalyst to assist the sonication process. Results showed that the presence of nano- TiO2 generally had little effect on degradation (about 10% in the case of anatase form).Operation parameters such as pH, ULTRASONIC power and catalyst dose in the presence of titanium dioxide were optimized with regard to the efficiency of CNB removal. The concentration of CNB during the reaction was detected by Uv- Vis spectrophotometer. The degradation rate of CNB was higher in the combined system than in the linear combination of separate experiments. In sonophotocatalytic process, the ULTRASONIC power and catalyst dosage are found to have Environment significant impact on the process efficiency whereas initial pH has relatively less effect. Under optimum conditions (0.2 g/L of Titanium Dioxide) destruction efficiency was 99.98 percent.
