文摘

•: Polymer inclusion membrane (PIM) containing Cyanex or Aliquat 336 extracted Co(II).
•: X-ray spectroscopy and XAFS determined the Co-extractant structure and coordination.
•: Polymerisation of the Co–Cyanex complex in Cyanex PIMs was demonstrated.
•: Polymerisation prevents back-extraction of Co(II) from the PIM into acidic solutions.
