摘要
本文用系数倍率紫外光谱法同时测定了制药废水中苯酚和水杨酸的含量 ,取得了满意的结果。苯酚测量回收率为 97.33%— 1 0 0 .77%、相对标准偏差 0 .83%。水杨酸测量回收率为 98.1 5 %— 1 0 0 .83%、相对标准偏差 0 .5 2 %。
The contents of phenol and salicylic acid in pharmacyical waste water were simultaneously determined by Kfactor UV spectrophotometry.The result is satisfatory.The recoveries of phenol and salicylic acid are in the range of 97.33%—100.77% and 98.15%—~100.83%, respectively.The relative standard deviations of phenol and salicylic acid are 0.83% and ~0.52% respectively.
