本文提出了硅橡胶膜在线萃取分离流动注射技术测定水样中苯酚的方法。由于水样中的苯酚透过硅橡胶膜进入萃取液的萃取量随时间的增加和温度的升高而增大,故采用停流技术及升高温度以降低酚的检出限。
This paper presents a method for the determination of phenol in water samples by on-line extraction and separation of silicone rubber membrane by flow injection technique. Due to the water sample phenol extraction through the silicone rubber membrane into the extract increased with time and temperature increases, so the use of stop-flow technology and increase the temperature to reduce the detection limit of phenol.
