Preferred Label : liquid-liquid extraction;
IUPAC definition : This term may be used in place of liquid-liquid distribution when the emphasis is
on the analyte(s) being distributed (or extracted).;
Scope note : the distinction between the distribution constant (k d) and the partition constant
(kdo) or the concentration distribution ratio (d c) is reaffirmed and it is recommended
that the terms partition constant, partition coefficient and extinction constant should
not be used as synonyms for the (analytical) distribution ratio, d c. a distinction
is drawn between the terms solvent and diluent, and the term extractant is now restricted
to the active substance in the solvent (i.e. the homogeneous organic phase which comprises
the extractant, the diluent and/or the modifier) which is primarily responsible for
the transfer of solute from the aqueous to the organic phase.;
