Why

In single-stage extraction, while keeping the feed composition and extraction concentration constant, what is the change in the concentration of the raffinate phase when an extractant containing a small amount of solute is used instead of a pure solvent?
There will be basically no significant changes; ordinary extractants can be reused
I still don’t quite understand it; it’s about how to conduct analysis based on the extraction phase diagram
The extraction process is a simple physical process; no changes occur
