| چکیده انگلیسی مقاله |
Background: Poly chlorinated biphenyls (PCBS) are the groups of organic chemical material and toxic, persistent, bio accumulate and pose a risk of causing adverse effects to human health and the environment. PCB compounds are caused the different health effects in human depending of age, sex, route of entry, intensity and frequency exposure. This study was conducted to determine the effect of microwave rays, hydrogen peroxide, TiO2 catalyst and ethanol on the Decomposition of PCBS. Methods: In this experiment used a MW oven, Pyrex vessel reactor (250ml volume), Pyrex tube connector and condensing system. A 900w domestic MW oven with a fixed frequency of 2450 MHZ was used to provide MW irradiation. Ray powers used in 540، 720 and 900w. The PCB were analyzed by GC-ECD Results: The degradation of total PCBS in terms of 540, 720 and 900W was 85.03%, 90.32% and 96.87% respectively. The degradation of total PCB in terms of ratio to solvent with transformer oil in 1:1، 2:1 and 3:1 was 53.97%، 78.98% and 95.13% respectively. The degradation of total PCBs in terms of not using of H2O2/ TiO2 and using 20% of H2O2 and 0.05, 0.1, 0.15 and 0.2 g TiO2 was 68.78%, 93.97%, 95.13%, 96.18% and 96.87 % respectively. Conclusion: The Microwave thermal reaction was applied for the dechlorination of PCBs and high efficiencies were obtained. Microwave power and amounts of reactants added are important factors influencing dechlorination efficiency. |
