“…They found that CTA/NPOE PIM-assisted extraction is especially useful for the detection of chlorpyrifos in river waters (RF = 93%). Mwakalesi and Potter [ 53 ] applied polymer inclusion membranes containing anacardic acid (AA) obtained from cashew nut shells as an acidic carrier, CTA as a polymer matrix, 2-NPOE as a plasticizer and dodecanol as a modifier for the extraction of 4-amino-2-chloropyridine, paraquat and diquat. These compounds can be treated as representative target solutes of organic pesticide residues.…”

Pollution of the environment, including water resources, is currently one of the greatest challenges due to emerging new contaminants of anthropogenic origin. Of particular concern are emerging organic pollutants such as pharmaceuticals, endocrine disruptors, and pesticides, but also other industrial pollutants, for example, synthetic dyes. The growing demand for environmentally friendly and economical methods of removing emerging contaminants and synthetic dyes from wastewater resulted in increased interest in the possibility of using techniques based on the application of polymer inclusion membranes (PIMs) for this purpose. PIM-based techniques are promising methods for eliminating emerging contaminants and synthetic dyes from aqueous solutions, including wastewater, due to high efficiency, membranes versatility, ease/low cost of preparation, and high selectivity. This review describes the latest developments related to the removal of various emerging contaminants and synthetic dyes from aqueous solutions using PIMs over the past few years, with particular emphasis on research aimed at increasing the effectiveness and selectivity of PIMs, which may contribute to wider use of these methods in the future.

“…Passive samplers based on membranes have been developed for analytes measurements, such as semipermeable membrane device (SPMD) (Lima et al, 2019), polar organic chemical integrative sampler (POCIS) (Jeong, 2020), Chemcatcher (Garnier et al, 2020), polyethylene (PE) (McKay et al, 2020), diffusion gradient in thin (DGT) (Kreuzeder et al, 2015) and Polymeric Inclusion Membrane (PIM) (Maiphetlho et al, 2021). Polymeric inclusion membranes (PIM)s have been used for a diffusive layer of passive samplers to measure metal ions (Ni, Co, Zn) (Keskin et al, 2021), ammonia (Almeida et al, 2016), pesticides (Mwakalesi & Potter, 2021). The advantages of PIMs are simple synthesis, efficient carrier immobilization, adaptability, and high mechanical characteristics (Rodríguez de San Miguel, 2022).…”

Polymer Inclusion Membranes (PIMs) have been fabricated for diffusive passive sample layers. A study of various concentrations of plasticizers and characterization of PIM performance on phosphate transport has been carried out. The composition of PIM consisted of cellulose triacetate (CTA) as the base polymer, Aliquot 336-Cl as a carrier, and 2-Nitro phenyl octyl ether (2-NPOE) as a plasticizer. The plasticizer concentration varied between 0 and 10% (w/w). The performance of PIM on phosphate transport was studied with a passive sampler filled with 15 mL 0.1 M NaCl as the internal phase. The passive samplers were deployed into the bulk phase of a phosphate solution of 0.6 mg/L for 0-48 hours. The phosphate concentration in the passive sampler was determined using the visible spectrophotometry method at 691 nm (in the bulk phase) and 710 nm (in the internal phase). PIMs were characterized for stress-strain, contact angle, surface morphology, and cross-section. The sampling rate of phosphate, phosphate time-weighted concentration (CTWA), and accuracy of phosphate measurement was also determined. The results showed that PIM A (0% w/w 2-NPOE) resulted in a sampling rate of 0.0005±0.0002 (L/hour), CTWA 0.09 mg/L, and an accuracy of 28.38%. PIMs B (10% w/w 2-NPOE) resulted in a sampling rate of 0.0003±0.0001 (L/hour), CTWA 0.18 mg/L, and an accuracy of 52.15%. PIMs A and B have a contact angle of 17.02⁰ and 18.71⁰, respectively. It means that these PIMs are hydrophilic membranes. In addition, PIMs B was more elastic than PIMs A, showed by the tensile strength of PIMs B was 31.05 MPa compared with PIMs A's tensile strength (29.01 MPa). PIMs A and B have no pores, as shown by surface morphology using SEM. However, based on the cross-section area, PIMs A showed a break section instead of PIMs B, which indicates that PIMs B is more elastic than PIMs A.
