stripping ratio

in solvent extraction
https://doi.org/10.1351/goldbook.S06056
Notes:
  1. This term is usually defined as the inverse ratio to the distribution ratio, i.e. in aqueous-organic systems the aqueous phase concentration of solute is the numerator and the organic phase concentration is the denominator. Their usage should be clearly defined.
  2. The term stripping coefficient is not recommended.
