separation factor, \(\alpha_{\text{A,B}}\)

in liquid-liquid distribution
https://doi.org/10.1351/goldbook.S05615
The ratio of the respective distribution ratios of two extractable solutes measured under the same conditions. \[\alpha_{\text{A,B}} = \frac{D_{\text{A}}}{D_{\text{B}}}\]
Notes:
  1. By convention the solutes designated as A and B in the above are chosen so as to make \(\alpha > 1\).
  2. The term @[email protected] is not recommended.
  3. The terms @[email protected] @[email protected] and @[email protected] are not synonymous and should not be used.
