摘要: Abstract When incinerator fly ash is heated at 398 °C under a stream of N 2 O polychlorinated dibenzo-p-dioxin (PCDD) and dibenzofuran (PCDF) concentrations are lowered. Dechlorination/dtx;omposition desorption competing processes. In this paper the was studied: within PCDD/F homologues, all isomers desorb an equal rate. Obviously, values activation energy from surface (ΔG#398,des do not differ significantly between these isomers.
