Abstract
The calculated selectivity of anions extracted from an aqueous phase into an organic solvent by a quaternary ammonium compound is highly dependent on the quantity of the reagent. Selectivity increases with a decrease in quantity of the salt (from 2.2 to 21.2 for salt quantities of 1 and 0.02 mol, respectively, in the system discussed) but never exceeds a certain value (25 in the system discussed). The same trend is observed when the volume of the organic phase is reduced. Experimental data agree well with the calculated results.
