“…The potential use of the reagent 2-APBH as a sensing molecule immobilised in a polymeric membrane of PVC (base polymer) and TBP (plasticizer) was proposed in a previous work. These components provide a homogeneous, flexible, mechanically strong, and optically transparent membrane [21]. In this study, the amounts of PIM components for Cd determination were optimised by applying a 3 (k−1) factorial design with two repetitions of the central point in two blocks.…”

“…PIMs have been used as optical chemical sensors for the selective separation and determination of metal ions by spectrophotometry (for example, Zn(II) determination in water, food supplements, and foot healthcare products [21]; Al(III) in aqueous samples [16]; or Cd(II), Zn(II), and Cu(II) in real water samples [22]), spectrofluorometry (such as Fe(III) in real samples [23] and Al(III) in natural water [24,25]), or colour-intensity measurements (such as Cu(II) [26] and Ag(I) and Hg(II) [27] in water samples), among others. In this sense, the use of Schiff bases in PIMs design can be very interesting since they are very effective chelating reagents used for the analysis, removal, and recovery of metal ions.…”

A disposable colour-changeable optical sensor based on an interesting polymer inclusion-membrane (PIM) was designed to determine Cd(II) ions in aqueous medium. The Schiff base 2-acetylpyridine benzoylhydrazone (2-APBH) immobilised on the polymer membrane was used as a sensing molecule. The amounts of the PIM components were optimised by a 32 fractional factorial design with two central points and two blocks. The best optical sensor composition consisted of 2.5 g of poly(vinylchloride) (PVC) as a base polymer, 3 mL of tributyl phosphate (TBP) as a plasticiser, and 0.02 g of 2-APBH as a reagent. The sensor showed a good linear response in the range from 0.02 mg L−1 (limit of detection) to 1 mg L−1 of Cd(II) under the following experimental conditions: pH 9.5 (adjusted using ammonium chloride buffer solution at 0.337 mol L−1), 60 min of exposure time plus 2 min of sonication (pulses at 2 s intervals), and 10 min of short-term stability. The relative standard deviation of the method was determined to be 4.04% for 0.4 mg L−1 of Cd(II). The optical sensor was successfully applied to the determination of Cd(II) in natural-water and art-paint samples.

A polymer inclusion membrane (PIM) prepared by casting a solution of cellulose triacetate (CTA), trioctylamine (TOA), and tri‐n‐butylphosphate (TBP), dissolved in dichloromethane was used for the extraction of bismuth(III) from hydrochloric acid solutions. The optimized PIM, in terms of mechanical properties and its efficiency for the extraction of bismuth(III), was consisted of CTA 40 wt%, TOA 25 wt%, and TBP 35 wt%. Contact angle measurements, FESEM, AFM, TGA, and stress–strain analysis were used for characterizing the PIM. A 3.5 cm diameter circular membrane segment of the PIM extracts quantitatively the bismuth ions (initial concentration 20 mg L−1) from 50 ml of 0.3 M HCl, after 120 min. The extracted bismuth was fully back‐extracted by shaking for 60 min of the loaded PIM with 50 ml solution of 2 M Na2CO3. It was confirmed that the extraction reaction involves the formation of the ion pair TOAnormalH+2[]BiCl52−. The developed PIM was stable for using in four extraction/back‐extraction cycles of bismuth(III). This stability was enhanced to ten extraction/back‐extraction runs by replacing the plasticizer TBP with 2–nitrophenyloctyl ether or dibutyl phthalate. The investigated PIM showed excellent selectivity towards Bi(III) over Cu(II), Pb(II), Zn(II), Ni(II), Co(II), Cd(II), Fe(III), Cr(III), Mo(VI), W(VI), NO3−, and SO42−.

“…In sample pre-treatment, PIMs are used to separate the target analytes from the matrix interferences, manually using batch technique [12][13] or automatically in a flowthrough system [14][15], which results in a high enrichment factor and low limit of detection [8]. With additional colorimetric, fluorometric, or chemiluminescent reagents, PIMs have also been applied as optical sensors in sensing various chemical analytes that require simple and rapid on-site detection with high selectivity and sensitivity [16][17]. The wide range of applications of PIMs has been shown by the growing number of PIM papers published between 1992 and 2021, with a total of 382 papers (Fig.…”

Improving the Performance of Polymer Inclusion Membranes in Separation Process Using Alternative Base Polymers: A Review

et al. 2021

View full text Add to dashboard Cite

Polymer inclusion membrane (PIM) has recently evolved as an alternative separation technique to conventional solvent extraction as it eliminates the use of toxic solvents, reduces separation cost, and simplifies the separation process. PIM is the new generation of a liquid membrane made by casting solution containing liquid phases (extractant and plasticizer/modifier) and base polymers. Despite its better performance and stability in comparison to the previous types of liquid membranes, PIM's robustness for applications on an industrial scale is still considered insufficient mainly due to its limited stability in the long-term separation process. In recent years, different approaches have been devoted to improving the stability of PIM while maintaining its performance. This review aims to summarize and evaluate the current literature on the improvement of the performance of PIMs with particular focus on the use of alternative base polymers, including non-conventional linear homopolymers, copolymers, or cross-linking polymers. Furthermore, more emphasis is given to the composition, fabrication process, and application of the PIMs. Finally, the performance of the PIMs with the alternative base polymers in terms of extraction rate and long-term stability is presented and compared to the PIMs fabricated using their corresponding common base polymers.
