摘要
采用小体积蒸馏,不使用分液漏斗,在比色管里直接进行萃取和目视比色,该方法省去了萃取液分离、比色计携带不便等麻烦,减少了器皿的使用,操作步骤简捷、测定结果快速可靠,特别适合开展野外现场分析。
The paper introduces a rapid method for determination of volatile phenols in water by small distillation,without using a separating funnel.The method saves the trouble of the trouble of extraction liquid separation,simplifies the procedure,reduces testing time.The method of detection of fast,accurate and reliable results,use less glass,easy to carry,is suitable for field analysis.
