摘　　要：文章研究了稀硫酸介质中，痕量苯酚阻抑溴酸钾氧化中性红褪色的指示反应，据此建立了阻抑动力学光度法测定痕量苯酚的新方法。结果表明，在0.1~5μg/ml范围内符合比耳定律，检出限为0.01065μg/mL。该法用于工业废水中苯酚的测定，结果满意。In dilute sulfuric acid medium,an kinetic sPectroPhotometric method for the determination of trace Phenol has been established,based on its inhibitory effect on the oxidation reaction of neutral red by Potassium bromate. The oPtimum condition of the mentioned reaction is investigated in detail in the PaPer. It is shown that Beer′s law was obeyed in the line-ar range is 0. 1~5μg/ml with the detection limit of 0. 01065μg/mL. The ProPosed method has been aPPlied successfully to the determination of trace Phenol in industrial waste water.
