摘要 苯酚、邻苯二酚和间苯二酚的紫外光谱重叠严重,难以对它们进行单个分析,因此采用紫外光谱法测定水中苯酚、邻苯二酚和间苯二酚的吸光度,并以蚂蚁算法(ACA)处理测定后的数据,得到苯酚、邻苯二酚和间苯二酚的含量。苯酚、邻苯二酚、间苯二酚的回收率分别在98.33%~101.11%、96.25%~100.56%,98.13%~102.86%之间。 The Ultraviolet - Spectrum of phenol, pyrocatechol and resorcinol were badly overlapped. It was difficult to analyse them individually. In the present work, UV - spectrophotometry was used to mensurate phenol, pyrocatechol and resorcinol in the same system. The data was analyzed by Ant Colony Algorithm(ACA) to work out the concentrations of phenol, pyroeatechol and resor- cinol. Results shows that the recovery rate of phenol was between 98. 33% - 101. 11% , while pyrocatechol between 96.25% - 100.56%, and resoreinol between 98.13% - 102.86%.
