Preferred Label : fraction extracted;
Detailed label : fraction extracted, E;
IUPAC definition : The fraction of the total quantity of a substance extracted (usually by the solvent)
under specified conditions, i.e. EA QA.Q'A where QA is the mass of strong A /strong
extracted and QA' is the total mass of strong A /strong present at the start.;
Scope note : the fraction extracted is also known as the recovery factor, especially for a multistage
process.; if the aqueous phase is extracted with n successive portions of solvent, the phase
volume ratio (solvent/feed) being r each time, the fraction extracted is given by:
