[0002] Stripping is the process of using a stripping agent to return the extracted substance from the loaded organic phase to the aqueous phase. It is the reverse process of extraction. The stripping process is simple, easy to operate and has a short cycle. It is an important part of the solvent extraction separation process. Stripping can strip each extracted component in the organic phase to the aqueous phase one by one, so that the separated components can be separated; it can also strip the extracted components in the organic phase to the aqueous phase at one time. After stripping and further treatment of the stripping liquid, the finished product of the separated substance is obtained. After stripping, the organic phase that does not contain or contains less extractants is washed and is called the regenerated organic phase, which is continuously recycled.
