在模拟城市垃圾飞灰的环境中，考察了铜和铁化合物对多氯二苯并二恶英（PCDDs）和多氯二苯并呋喃（PCDFs）的主要氯化剂氯（Cl2）生成的催化作用. Cl 2的形成是由于HCl与O2的金属催化反应而发生的。催化活性在约400 °C的温度下最大，支持废物燃烧下游飞灰颗粒上重新合成多氯二苯并对二恶英和多氯二苯并呋喃的理论。
The catalytic effects of copper and iron compounds were examined 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. Formation of Cl2occurred as a result of a metal-catalyzed reaction of HCl with O2. Catalytic activity was greatest at a temperature of approximately 400 °C, supporting a theory of de novo synthesis of PCDDs and PCDFs on fly ash particles downstream of waste combustion.
