Ion-pairing extraction of platinum metals and related metals from hydrochloric acid by extractant having tertiary amino N atom

Sasaki, Yuji ; Ban, Yasutoshi ; Matsumiya, Masahiko*

Metal ions are present as anionic species in hydrochloric acid. Diamino-extractants containing tertiary amino N atom, such as NTAamide, protonate in acidic solutions and become cationic extractants. In this study, the ion-pair extraction of metal chloride anions, especially platinum metals and the related metals, with the cationic extractants was performed and their extraction properties are studied.
