✦ Synopsis

Transport of silver and copper ions through a plasticized cellulose triacetate membrane (CTA) containing macrocylic polyethers as carrier and 2-nitro phenyl octyl ether (NPOE) as plasticizer has been investigated. The membrane CTA-NPOE-Carrier was characterised using chemical techniques for metal ion transport as well as Fourier transform infra-red (FTIR), X-ray diffraction, differential scanning calorimetry (DSC) and scanning electron microscopy (SEM). A comparative study of transport mechanism across such a membrane and a supported liquid membrane (SLM) containing the same carrier has been made.

## Abstract A cellulose triacetate (CTA)–poly(ethylene imine) (PEI) membrane containing a polyether macrobicyclic (cryptand) as a carrier and 2‐nitrophenyloctyl ether (NPOE) as a plasticizer was prepared. The CTA–PEI–cryptand–NPOE membrane was characterized with chemical techniques as well as Fouri
