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

in liquid-liquid distribution
The ratio of the respective distribution ratios of two extractable solutes measured under the same conditions. \[\alpha_{\text{A,B}} = \frac{D_{\text{A}}}{D_{\text{B}}}\]
  1. By convention the solutes designated as A and B in the above are chosen so as to make \(\alpha > 1\).
  2. The term @S05613@ is not recommended.
  3. The terms @S05563@ @C01124@ and @S05569@ are not synonymous and should not be used.
