英文摘要	dechlornations of polychlorinated dibenzo-p-dioxins (pcdds), polychlorinated dibenzofurans (pcdfs) and coplanar polychlorinated biphenyls (co-pcbs) were carried out in ethanol-water solution of naoh in the presence of pd/c catalyst with using of h-2. the dechlorination of octachlorodibenzo-p-furan (ocdf) proceeded with pd/c under mild conditions (atmospheric pressure and <100 degrees c) to give a chlorine-free product, dibenzo-p-furan (df), in high yield. after a reaction of 3 h at 50 degrees c, 98.8% of ocdf was degraded and the yield of df was 85.2%. pcdd/fs and co-pcbs extract from fly ash of commercial solid-waste incinerator was degraded in this catalytic system at 50 degrees c for 6 h. pd/c exhibited excellent reaction activity in this catalytic system. in the dechlorination of environmental sample, the concentrations of toxic congeners and teq decreased to a promising level.
