An extraction method was first examined for establishing possible distributions of surface-active dodecyltrimethylammonium chloride (DTMAC) and non-surface active tetrabutylammonium chloride (TBAC) between aqueous and organic phases. Both quaternary ammonium salts seem to be present in the form of a free ion in the aqueous phase and in the forms of an ion pair(monomer) and a dimer in the organic phase. A possible distribution of DTMAC in the organic phase was confirmed spectrometrically by following the formation of a 1 : 1 DTMAC–iodine adduct in chloroform solution. On the basis of the possible distribution of quaternary ammonium salts, an ion pair forming extraction of Pyrocatechol Violet (PV) can be successfully interpreted in terms of the anion-exchange mechanism.
