Title:
塩基性陰イオン交換樹脂の再生方法
Document Type and Number:
Japanese Patent JP5163125
Kind Code:
B2
Abstract:
A simple and efficient method for regenerating a basic anion-exchange resin, whereby at the time of removing a fluorinated emulsifier from a basic anion-exchange resin having the fluorinated emulsifier adsorbed thereon, it is unnecessary to provide a safety device/recovery technique necessary for handling an organic solvent by the use of a combustible organic solvent represented by an alcohol, and a burden imposed by e.g. treatment against COD load, is eliminated. A basic anion-exchange resin having a fluorinated emulsifier adsorbed thereon is contacted with an aqueous alkaline solution having a temperature of from 60 to 105°C to elute the fluorinated emulsifier thereby to regenerate the basic anion-exchange resin.
