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

摘要:

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(GCMS)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.

Abstract:

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(GCMS)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.
