| 摘 要： | 由于水中脉冲放电产生等离子体通道,水会发生复杂的等离子体化学反应,产生各种自由基,本文检测到放电形成的羟基自由基.对苯酚废水进行放电降解研究,利用紫外分光计、有机碳分析仪、液相质谱联用仪和气相质谱仪等仪器对降解产物进行检验.结果表明,苯酚废水在放电作用下生成的中间产物为:多羟基苯酚、酮、醛和酯等,最终产物为二氧化碳和水.此结果对苯酚废水在脉冲放电,甚至直流或交流电下的苯酚降解机理的进一步研究有参考价值.

| Abstract: | A pulse discharge in water creates a plasma channel which causes complicated chemical reactions,and produces various radicals.Hydroxyl radical was detected in our system.An ultraviolet spectrophotometer,total organic carbon analyzer,gas chromatograph-mass spectrometer,liquid chromatograph-mass spectrometer and other instruments were employed for detection of reaction products in the treatment of phenol wastewater.The intermediate products are polyphenols,ketones,aldehydes,esters etc.and the final products a... |
