摘要: 挥发酚是水体中的重要污染物，对生态环境和人体健康有着严重的危害，美国环保署已将11种酚类化合物列入环境优先污染物之中。文章概括了挥发酚的气相色谱法、蒸馏后溴化容量法、重量法、薄层色谱法、液相色谱法、光度法等检测方法的特点，重点介绍了流动注射分光光度法在挥发酚测定中的原理及在水质分析中的应用，讨论了该法的影响因素，包括缓冲溶液pH、氧化剂、空气峰以及实际水样的影响，并对这一领域的发展趋势进行了展望。引用文献54篇。Abstract: Volatile phenols are found in a wide range of industrial wastes and natural waters. The US Environmental Protection Agency (USEPA) lists eleven phenols as priority pollutants due to their toxicity and serious hazard on the ecological environment and human health. Some methods for volatile phenol analysis were introduced in this paper, such gaschromatography, distillationBrvolumetry, gravimetry, thin layer chromatography, liquid chromatography, spectrophotometry and so on. The developments in the application of flow injection analysisspectrophotometric determination of volatile phenols were reviewed in detail. The factors affecting the determination of volatile phenols such as pH, oxidant, air peaks and sample matrix were discussed. The application trend of flow injection analysisspectrophotometry in this area was prospected and 54 references were cited.
