机械球磨降解飞灰中二噁英及其球磨后飞灰的二噁英从头合成

摘要： 机械化学法应用于职称论文发表期刊降解各种材料中的氯代有机污染物已经得到了广泛的研究。

在本文的研究中，在没有添加剂的情况下，用全方位行星式球磨机机械研磨了城市生活垃圾焚烧的飞灰。对不同研磨时间的飞灰样品测量了二噁英的含量，最后进行从头合成实验以测试处理过的飞灰的化学反应特性。

Abstract： Mechanochemical (MC) treatment has been widely proposed to degrade chlorinated organics in various matrix materials. In this study, fly ash from municipal solid waste incineration was grinded without any addition, using an all-dimensional planetary ball mill. The residual concentration of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/F) in the fly ash with different grinding time was monitored . Finally, de novo formation experiments were performed to test the chemical reactivity of the treated fly ash..
