The ratio of the total mass of a solute in the extract to that in the other phase.
Notes:
-
It is the product of the (concentration) distribution ratio and the appropriate phase ratio.
-
It is synonymous with the concentration factor or mass distribution ratio, this latter term being particularly apt.
-
The term concentration factor is often employed for the overall extraction factor in a process or process step.
