Abstract

Background: In this research, the decomposition of Aroclor 1254, including 20 kinds of poly chlorinated biphenyls (PCBs), in real waste transformer oil in the presence of PEG1000, NaOH, zero valent iron and H2O by microwave (MW) irradiation was studied.Methods: Central composites design (CCD) method was carried out for experimental design. The effects of microwave power levels (200- 1000 W), reaction time (30-600 s), polyethylene glycol (PEG) (1.5-7.5 g), zero valent iron powder (0.3-1.5 g), NaOH (0.3-1.5 g) and H2O (0.4-2 ml) were surveyed on the decomposition efficiency of PCBs.Results: The results specified that polyethylene glycol and NaOH, as reactants, greatly influenced the decomposition of PCBs. Nevertheless, zero valent iron had no effect, and H2O decreased the decomposition efficiency of PCBs. Furthermore, experimental results showed that at the optimum amounts of variables (PEG = 5.34g, NaOH= 1.17g, Fe= 0.6g, H2O= 0.8 ml, microwave power 800 w), 93% of PCBs were decomposed over the rea ction duration of 6 min. Therefore, PCBs degradation efficiency without water rose up to 99.99% under the MW at 6 min.Conclusion: The results indicated that MW, PEG and NaOH were important variables on PCBs degradation from real waste transformer oil. It is therefore suggested that microwave radiation with the assistance of PEG and alkali can be introduced as a potential technology for PCBs removal from real waste PCB-contaminated oil.
