本文研究了紫外光（ＵＶ）、亚铁离子（Ｆｅ~（２＋）和过氧化氢（Ｈ_２Ｏ_２）相结合对酚类化合物的光化学降解作用，采用正交设计优化实验条件，多元线性回归分析数据。结果表明：影响光化学降解的因素从大到小依次为；ｐＨ、酚浓度、光照时间、过氧化氢的量和亚铁离子的量．采用该法处理实际水样，光照２０ｍｉｎ，其酚类化合物的降解百分数达９０．４％，并用ＧＣ－ＭＳ讨论了三种酚的降解历程。
In this paper, the photochemical degradation of phenolic compounds by ultraviolet (UV), ferrous ions (Fe 2+ and H 2 O 2) was investigated. Orthogonal design was used to optimize the experimental conditions and multivariate linear regression analysis. The results showed that the factors influencing the photochemical degradation were as follows: pH, phenol concentration, light time, the amount of hydrogen peroxide and the amount of ferrous ions.Using this method, the actual water samples were treated with light for 20 min, and the phenolic compounds The degradation percentage reached 90.4%. The degradation process of three phenols was discussed by GC-MS.
