摘要：

Previous studies showed that zinc, copper and sodium concentrations were correlated with dioxin concentrations on fly ash from municipal solid waste incinerators. Statistically designed experiments were performed to study the effects of these elements on PCDD formation. The elements were deposited as zinc nitrate, copper hydroxide and sodium hydroxide on silica gel. Pentachlorophenol was used as a model precursor. Zinc nitrate promoted PCDD formation. Both copper hydroxide and sodium hydroxide inhibited PCDD formation.
