Comparison of carrier-facilitated silver (i) and copper (ii) ions transport mechanisms in a supported liquid membrane and in a plasticized cellulose triacetate membrane

Efficient Facilitated Transport of Lead and Cadmium Across a Plasticized Triacetate Membrane Mediated by D2EHPA and TOPO

“…In fact, the common plasticizer o-nitrophenyl octyl ether (NPOE) suffers virtually no loss from the membrane into adjacent water phases [9]. Also, PIM demonstrate permeability of ionic and neutral species comparable to SLM [10]. Any loss of transport in PIM in comparison to SLM is due to slower diffusion across the membrane, however, the higher carrier capacity of CTA membranes helps increase transport to counteract this effect [11,12].…”

Studies on the selective Am3+ transport, irradiation stability and surface morphology of polymer inclusion membranes containing Cyanex-301 as carrier extractant

“…is defined as P Am /PEu. reported for the surface of NPOE plasticized CTA-PIM containing cryptands and crown ethers as carriers, where no trace of pore or fibre was seen [23]. Membrane stability, however, deteriorated significantly which was seen clearly from the significant decrease in P Am and separation factor value.…”

Synthesis of modified polymer inclusion membranes for photo-electrodeposition of cadmium using polarized electrodes

“…Transport studies through cellulose triacetate membranes as polymeric matrix with high flux and good stability have been reported recently [18][19][20][21][22][23][24][25][26][27][28][29][30][31]. The permeation of Pb 2+ and Cd 2+ through PIMs in presence of CuFeO 2 as polarized electrode has been successfully applied by some of us [32].…”
