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 %。
In this paper, simultaneous determination of phenol and salicylic acid content in pharmaceutical wastewater by coefficient-ratio UV spectrophotometry, and achieved satisfactory results. The recovery of phenol was 97.33% -100.77%, the relative standard deviation was 0.83%. The recovery of salicylic acid was 98.1 5% -10083%, relative standard deviation was 0.52%.
