The effects of chlorine speciation and physical chemistry characteristic of fly ash on the de novo formation of PCDD/Fs were studied in a tubular oven.
氯源是二噁英生成的关键因素之一,该文在管式炉中研究了飞灰中的氯形态以及物理化学特性对从头合成二噁英的影响,利用高分辨色谱/低分辨质谱(HRGC/LRMS)测定了气相以及固体残渣中的二噁英,试验结果表明,飞灰中的无机氯含量高于有机氯含量,而有机氯中,可以提取有机氯含量高于不可提取有机氯含量,飞灰中的不可提取有机氯是最能促进二噁英生成的氯源。
