The paper gives results of an examination of the catalytic effects of copper and iron compounds for their behavior in promoting formation of chlorine (Cl2), the major chlorinating agent of polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs), in an environment simulating that of municipal waste fly ash. Cl2 formed as a result of a metal-catalyzed reaction of HCl with O2. Catalytic activity was greatest at a temperature of about 400 C, supporting a theory of de novo synthesis of PCDDs and PCDFs on fly ash particles downstream of waste combustion.
