高铁酸钾降解苯酚的GCMS分析

Analysis of Degradation Intermediates of Phenol with Potassium Ferrate by Gas Chromatography and Mass Spectrometry

采用蒸发、衍生化等方法分离、富集出高铁酸钾氧化降解苯酚的中间产物,利用气相色谱质谱联用仪(GC MS)定性分析出了对苯二酚、苯醌、联苯二酚和苯氧基苯酚以及草酸、顺丁烯二酸和反丁烯二酸等降解中间产物,并依此推测了高铁酸钾降解苯酚的主要途径.

The phenol was oxidized by potassium ferrate. The intermediates were extracted from the degraded mixtures with vaporization, derivation, and ion-exchange methods and analyzed with gas chromatography and mass spectrometry（GC -MS） techniques. Benzoquinone, hydroquinone, diaphenol, phenoxyl phenol, maleic acid, fumaric acid, and oxalic were determined. Based on the results, the degrading path of phenol was deduced.
