摘要：

Dioxins, such as polychlorinated dibenzodioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs), which could be efficiently extracted from fly ash based on the method approved by the Japanese Industrial Standard, were degraded by the palladium on carbon (Pd/C)-catalyzed hydrodechlorination in the presence of triethylamine at room temperature under ordinary pressure with a greater than 97% efficiency. The distinct features of the present degradation method of dioxins are its mildness, simplicity, safety, and efficiency without any expensive facilities.
