This article presents application of polymer inclusion membranes (PIM) containing polymer matrices: cellulose triacetate (CTA) or poly(vinyl) chloride (PVC), o-nitrophenyloctyl ether (NPOE) as a plasticizer and phosphonium ionic liquids, i.e., trihexyltetradecylphosphonium chloride (Cyphos IL 101), bis(2,4,4-trimethylpentyl)phosphinate (Cyphos IL 104) and tributyltetradecylphosphonium chloride (Cyphos IL 167), as carriers for Zn(II) transport from chloride medium. Cyphos IL167 application as an ion carrier in PIMs is reported for the first time. The membrane composition is found to affect Zn(II) transport significantly. SEM and AFM images show the differences in the surface morphology of PVC and CTA based membranes. Better transport abilities of CTA membranes (Zn(II) recovery factors exceed 80%) compared with those of PVC, indicate that the structural differences between the two polymers play a crucial role for the membrane permeability. The best initial flux and permeability coefficient are obtained for the membranes with Cyphos IL 101 and Cyphos IL 104 as carriers.

“…Moreover, in the SEM images of the surface and the cross section of the investigated PIMs no pores were found. The obtained results are consistent with observations of Ugur [22], who also did not find any pores in PIM when analyzing SEM images shown at the μm scale.…”

Membrane techniques can be used to separate different compounds, i.e., toxic metal ions from waste waters. As any other method of separation, also this one, based on polymer inclusion membranes (PIMs), has certain limitations. One of them is the stability of membranes. In the present paper, the dependence of the physical and chemical properties on composition of PVC-based polymer inclusion membranes doped with phosphonium ionic liquids (CYPHOS IL 101, CYPHOS IL 104, CYPHOS IL 105 and CYPHOS IL 109) was studied. The thermal stability of investigated membranes was examined by thermogravimetry together with differential thermogravimetry analysis. Obtained results showed that studied PIMs are stable to the temperature of about 170 °C. The membrane morphology was examined by attenuated total reflectance Fourier-transform infrared (ATR-FTIR) spectroscopy, as well as scanning electron microscopy (SEM). The visibility of all characteristic bands in the ATR-FTIR spectra confirmed the presence of individual components in the membranes: a polymer, a plasticizer and the carriers. It also suggested that there were no signs of the covalent bond formation between the polymer, the plasticizer and the carrier. Only van der Waals or hydrogen bonds could be present. Moreover, in the SEM images of the investigated PIMs a rough surface without pores was observed.

“…These membranes have been proposed as possible packaging materials. The CTA membranes were made using the method described by Senhadji et al [24] .The casting solution was made by dissolving 1 gm of CTA in 100 mL of dichloromethane (DCM) at room temperature. This solution also contained 1.5 mL of 2-NPOE.…”

Fabrication of new antimicrobial cellulose triacetate packaging membranes is the main focus of the present study. The integration of 2-aryl substituted benzothiazoles in a polymeric matrix of cellulose triacetate is used to fabricate these membranes. FT-IR and SEM are used to characterize these membranes. When assessed against Bacillus cereus, Bacillus subtilis, Escherichia coli, and Pseudomonas aeruginosa, the modified packaging membranes demonstrated positive antimicrobial activities.
