| 摘 要： | 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。

| Abstract: | A flow injection analysis system with silicone-rubber separation membrane is de-signed for the determination of phenol in water. The phenol in water contacted with the membrane is dissolved in the membrane, then diffuses through the membrane wall and into the solution of sodium hydroxide (extractant). The permeation rate on the phenol is depen-dent on the stopped -flow time and temperature. Use of the stopped-flow technique and in-crease in temperature can reduce the detection limit of phenol. |
