A micellar solution of sodium dodecylsulfate (SDS) can separate into two phases due to a temperature change or the addition of salts. SDS plays the roles of a pairing-ion for ammine-complexes and of an extraction medium. The ion-pair extraction mechanism was investigated by SAXS and DSC measurements. This extraction was used for the separation of Cu(II) as a minor component from Ni(II) as a dominant component.
