Abstract
Microwave (MW) is applied to enhance pentachlorophenol (PCP) removal using zerovalent iron (ZVI, Fe0) or granular activated carbon (GAC) as the dielectric media. Applying MW energy at 700 W for 20 s, the results show that Fe0 is capable of enhancing the CB removing 2.7 times (91% vs. 34 %) than GAC. Because Fe0 has higher dielectric loss (39.5 F/m vs. 8.3 F/m), it absorbs more MW energy to speed up the oxidation rate resulting in a faster temperature rise than GAC. Thus, in the presence of MW, Fe0 is superior to GAC for PCP removal. Additionally, excessive MW exposure will damage the surface structure of either Fe0 or GAC causing excessive electric charges to accumulate in the media that brings about the phenomenon of sparks.
