Cellulose triacetate membranes doped with organo-phosphoric carriers (2-ethylhexyl) phosphoric acid noted (D2EHPA) or trioctyl phosphine oxide noted (TOPO) as fixed carriers and 2-nitro phenyl octyl ether noted (NPOE) or tris ethylhexyl phosphate noted (TEHP) as a plasticizers have been prepared and applied for investigation to the facilitated transport of Pb(II) and Cd(II) ions from aqueous nitrate source phase. The membranes Polymer -Plasticizer -Carrier were characterised using chemical techniques as well as Fourier Transform Infra -Red (FTIR), X -ray Diffraction and Scanning electron microscopy (SEM).A study of the transport across a polymer inclusion membrane has shown that the lead or cadmium transport efficiency was increased using D2EHPA as carrier at pH 1-2.

“…However, a cross section of this membrane shows a more complicated, stratified structure. This structure is different in comparison with article (11,45,47) where the presented structure was strongly porous. In case of the membrane containing ONPOE as plasticizer and 1-alkylimidazoles as carrier (Figs.…”

Research, about citric acid transport, through the polymer inclusion membranes, have been carried out. Two different plasticizers -ONPOE and TBP and a series of carriers of tri-octylamine and 1-alkylimidazoles with carbons chain length of 10, 11, 12, 14, and 16 atoms were used. It was found out that for 1-alkylimidazoles values of the permeability coefficients obtained for TBP as plasticizer change in the range of 8.81 Ã 10 À7 m/s to 1.92 Ã 10 À6 m/s. When ONPOE was used as the plasticizer, the values change in the range of 1.43 Ã 10 À9 m/s to 2.24 Ã 10 À8 m/s. The value of the permeability coefficient for the membrane with TBP equals 3.49 Ã 10 À7 m/s and is comparable with the value obtained for the TOA with this plasticizer, which equals 4.77 Ã 10 À7 m/s TBP, therefore, it is able to simultaneously act as a plasticizer and carrier in membrane. Tested membranes are characterized by a high durability. The repeated 5-times, 24-hours cycles of research did not show any decrease in transport capacity of citric acid.

“…The surface morphology of both membranes has light and dark regions. These regions may have occurred because of either different speed of the solvent vaporization [13,18] or membranes having a porous structure where the pores of membrane have been filled by NPOE or NPOE + FFAT [57,58]. The comparison between the two AFM pictures showed the differences between the surfaces of membranes result from the existence of carrier in PIM.…”
