| 摘 要： | 利用气相色谱-质谱探讨了丙烯腈废水中有机物的高压放电法降解机理.结果表明:丙烯腈的氰基首先被破坏生成丙烯酸,丙烯酸进一步被氧化生成乙酸,乙酸降解为甲酸,最后生成CO2.丁二腈首先降解为丁二酸,丁二酸再生成丙酸,并逐步降解为乙酸、甲酸,最后生成CO2.二氰乙基胺在降解过程中依次生成丙腈、丙酸、乙酸和甲酸,最后生成CO2....

| Abstract: | High potential discharge degradation mechanism of major organic compounds in acetonitrile wastewater was investigated by means of gas chromatography-mass spectrometry.It was found that the cyano group of acrylonitrile was initially decomposed to generate acrylic acid which was further oxidized to form acetic acid.Acetic acid was then decomposed to generate formic acid which was finally degraded into CO2.The main degradation route of butanedinitrile is similar to that of acrylonitrile.Namely,it was successiv... |
