电泳萃取技术处理专利兰A醇溶液

:电泳萃取是电泳与萃取技术耦合形成的一种新型分离技术。本文应用该技术以水为萃取剂从醇溶液中回收专利兰 A。在自行设计的连续电泳萃取池内实验研究了电场强度 ,两相流速等因素对于萃取率及传质通量的影响。实验结果表明 ,电场强度的增大可以有效地提高溶质的萃取率 ,传质通量也随之增大 ;有机相流速的增大 ,将使萃取率下降 ,传质通量则可能存在极大值 ;水相流速的变化对萃取率及传质通量的影响均不显著且规律性不强 ,电泳萃取从醇溶液中萃取专利兰 A的萃取率可达 95 %以上 ,是一种十分有效的分离染料的方法

A STUDY ON TREATMENT OF BUTANOL CONTAINING ALPHAZURINE A WITH ELECTRO-EXTRACTION

The electro-extraction technology was used to reclaim alphazurine A from butanol solution. Effect of electric field strength and two phase velocity on mass transfer was studied in an electro-extraction equipment. The experimental results showed that mass flux and recovery increased significantly by increasing electric field stength. With an increase of organic phase velocity, the recovery of solute decreased, while maximum mass flux may exist. The effect of aqueous phase velocity on recovery and mass flux is indistinctive. In proper conditions recovery of alphazurine A is can reach over 95%.
