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.

“…Indeed, the transport test through the membrane without plasticizer and in the presence of carrier (RC8) shows a basal flux of phenol. Further variation in the amount of NPOE gives higher transport efficiency up to 0.03 ml of NPOE which might be due to the favorable plasticizer plasticization effect, beyond which a decrease in transport was attributed to intermolecular interaction between target and plasticizer molecule resulting in lower mass transfer (Nghiem et al 2006). …”

Nowadays, there are increasingly stringent regulations requiring more and more treatment of industrial effluents to generate product waters which could be easily reused or disposed of to the environment without any harmful effects. In the present work, the removal of phenol from aqueous solution across polymer inclusion membrane (PIM), based on mixture of cellulose triacetate and cellulose acetate as support (75/25%), calix[4]resorcinarene derivative as a carrier and 2-nitrophenyl octyl ether (2-NPOE) as plasticizer was investigated. The experimental part of this investigation involved the influence of carrier nature, plasticizer concentration, pH phases, and phenol initial concentration on the removal efficiency of phenol from synthetic wastewater. A PIM containing 0.1 g (of mixture polymer), (0.15 g/g mixture of polymer) of carrier and (0.03 ml/g mixture of polymer) of 2-NPOE provided the highest percentage of phenol removal efficiency over a 6-day transport; the removal was found to be about 95%, indeed the removal was found to be highly dependent of pH phases. The feed solution in these transport experiments was at pH 2, while the stripping solution contained 0.20 M NaOH. This study claims that the PIM with a mixture of cellulose derivatives can be used effectively to remove phenols from wastewaters.

“…Literature review reveals that solid polymer electrolytes have been widely studied as cation, mostly lithium ion, conductors with intention of applying as secondary batteries; however their utilization as anionic conductors is rather unexplored [5][6][7][13][14][15][16]. Anionic conductors are important not only for DSSCs but also for other electrochemical applications such as electrochromic devices and separation processes, which are also less studied [15,17].…”

In this study, the electrical, dielectric and morphological analysis of composite solid polymer electrolytes containing polyethylene oxide, alumina nano-fillers and tetrapropylammonium iodide are conducted. The temperature dependence of conductivity shows activation energy of 0.23, 0.20 and 0.29 eV for electrolytes containing 0, 5 and 15 wt.% alumina, respectively, when data fitted to the Arrhenius equation. These activation energy values are in good agreement with those determined from dielectric measurements. The result confirms the fact that conductivity is activated by both the mobility and the charge carrier density. The conductivity isotherms demonstrated the existence of two peaks, at 5 and 15 wt.% Al 2 O 3 composition. The highest conductivity values of 2.4 × 10 −4 , 3.3 × 10 −4 and 4.2 × 10 −4 S cm −1 are obtained for the sample with 5 wt.% Al 2 O 3 at 0, 12 and 24°C, respectively, suggesting an enhancement of conductivity compared with that of alumina free samples.
