摘　　要：借助高效液相色谱(HPLC),通过标准物比对法和添加标准物法,研究了高铁酸钾降解苯酚的开环产物。结果表明,高铁酸钾降解苯酚的主要稳定的中间产物有顺丁烯二酸、反丁烯二酸、草酸和甲酸。并据此推导出苯酚被高铁酸钾氧化降解的可能途径。Potassium ferrate（K2 FeO4 ） is an attractive chemical for wastewater treatment because it is a strong oxidant for organic pollutants and also a source of ferric ion for coagulation to remove colloidal constituents of the wastewater. Fumaric acid,maleic acid,oxalic acid and formic acid were found to be the primary products of ferrate oxidation of phenol（100 mg/L） ;they were further oxidized to result in additional byproducts which appeared as the other peaks in the HPLC chromatogram of ferrate treated phenol solution. The reaction mechanism with the associated degradation pathway was proposed,
