摘要
研究了Fenton试剂 -超声波振荡法降解对硝基苯胺的中间产物和最终产物 ,分析方法采用气相色质-质谱联用法和离子色谱法。实验结果表明 :对硝基苯胺降解中间产物中有硝基苯、苯酚和对苯醌 ,最终产物中有硝酸根。研究了中间产物在降解过程中浓度的变化规律 。
The Fenton-ultrasonic degradation intermediate products and final products of p-nitroaniline solution were determined by gas chromatography-mass Spectrometry and ion chromatography. The results showed that the degrade products of p-nitroaniline contain nitrobenzene, phenol, p-benzoquinone and naphthalene. The final products were nitrate mostly. The dependence of concentration of intermediate products on ultrasonic time was studied. The some degradation mechanisms were discussed.
