摘　　要：对吸收峰重叠严重的苯酚、邻苯二酚、间苯二酚和对苯二酚4组分体系进行研究,以径向基函数神经网络光度法建立校正模型,同时测定了水样中的苯酚、邻苯二酚、间苯二酚和对苯二酚的含量,回收率为95.7%～109.2%。The four components system of phenol, pyrocatechol, resorcinol and hydroquinone was studied by spectrophotometry. Serious overlapping of the absorption peaks made it difficult to determine the four components simultaneously. The radial basis function network being used as the mathematical model, the content of the four components in water samples was determined with the recovery of 95.7%~109.2%.
