Abstract	Microwave irradiation was adopted to combine with the traditional base-catalyzed decomposition (BCD) process for the degradation of polychlorinated biphenyl, thus formed the so-called microwave-assisted base-catalyzed decomposition (MA-BCD) process. 2, 4, 5-trichlorobiphenyl (PCB29) dissolved in hexane or cetane was used to test the effectiveness of the MA-BCD process, where the solvent acted both as reaction medium and as hydrogen donor. The role of sodium hypophosphite (NaH2PO2) as hydrogen donor was also investigated. Granular activated carbon (GAC), zero-valent iron powder, copper powder and Pd/C catalyst were selected as catalysts and microwave absorbents. The results indicated that most of PCB29 could be decomposed in a few minutes by the MA-BCD process, with NaH2PO2 as hydrogen donor, any kind of the four catalysts and NaOH added. Microwave output power level was a key factor, and the treatment with a higher microwave power for a short time was more effective than that with a lower microwave power for a long time. Higher degradation efficiencies were obtained when NaOH was added in aqueous solution in stead of particles, as the existence of water was helpful for the release of H2 from NaH2PO2. The degradation of PCB29 by the MA-BCD process was through dechlorination, and biphenyl was detected as the main product.
