摘要
目的：建立导电凝胶中苯酚的含量测定方法。方法：采用一阶导数光谱法于（279±1）nm波长处直接测定苯酚的含量。结果：苯酚在25．47～45．85μg·ml^-1浓度范围内，线性关系良好，相关系数r=0．9999，平均回收率99．43％，RSD为0．36％。
Objective： To establish a quantitative analysis method for phenol in Electrographic gel. Method： The phenol was determined directly at 279nm by first derivative spectrometry. Results： The calibration curve of phenol was linear in the range from 25. 47～45. 85μg · ml^-1 with r=0. 9999, the average recovery and relative standard deviation were 99.43% and 0. 36% respectively.
