摘要：

Liquid-liquid ion-exchange extraction of various anions including hexacyanoferrate(III) with a chlorobenzene solution of trioctylmethylammonium chloride (TOMA-Cl; Aliquat-336 chloride) is described. The ion-pair extraction constant of TOMA-Cl (KQ.Clex = 104) and the ion-exchange extraction constants of TOMA-Cl for each anion (KCl.Xex) are reported. The order of selectivity of anion extraction is Fe(CN)3-6 (log KQ.Xex = 22.41) > ClO-4(8.47) > PAR- (7.80) > I-(7.32) > NO-3(5.81) > Br-(5.34) > Cl-(4.00). © 1979.
