“…The reduction in the extraction efficiency can be related to the saturation of the carrier on the surface of the membrane which resulted in a reduction in the diffusion boundary layer and hence slower transport kinetics [ 53 ]. This finding is consistent with the outcome of other research [ 36 , 51 , 54 , 55 ].…”

“…When more carriers are incorporated into the membrane, there is formation of more capacity for the MG 2+ -B 2 EHP complex; thus, the rate of MG extraction was enhanced. This result is in agreement with other researchers on the PIM extraction/removal of methylene blue, indium (In(III)), chromium (Cr(III)) and copper (Cu(II)) with the D 2 EHPA carrier [ 8 , 50 , 51 , 52 ]. Hence, M6 with 21% B 2 EHP content was selected as the PIM with the best performance for further studies.…”

“…This shows that the experimental data for different percentages of the carrier are well fitted with the PSO model. This also indicates that the extraction mechanism of PIMs undergoes chemisorption mechanisms which involve oxidation and reduction processes [ 51 , 77 , 78 , 79 ]. As observed, M6 has the highest mass transfer coefficient, k 2 , and the lowest theoretical equilibrium constant, C e , of 0.0070 and 0.4235 mg/L, respectively.…”

“…A similar occurrence was reported by Gherasim et al [ 81 ] who deduced that the sorption mechanism of Pb(II) metal with PIMs containing the B 2 EHP carrier was based on the PSO kinetics model. Furthermore, Salima et al [ 51 ] and Mahanty et al [ 82 ] also concluded that PSO model can suitably describe the mechanism of extractions by PIMs. Figure 14 illustrates the mechanism of the MG extraction, while Figure 15 shows the plotting of the theoretical and experimental data C t vs. t of the extraction process at different MG concentrations.…”

Textile industry effluent contains a high amount of toxic colorants. These dyes are carcinogenic and threats to the environment and living beings. In this study, poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-co-HFP) was used as the based polymer for PIMs with bis-(2-ethylhexyl) phosphate (B2EHP) and dioctyl phthalate (DOP) as the carrier and plasticizer. The fabricated PIMs were employed to extract the cation dye (Malachite Green; MG) from the feeding phase. PIMs were also characterized by scanning electron microscopy (SEM), atomic force microscope (AFM), contact angle, water uptake, Fourier-transform infrared spectroscopy (FTIR) and ions exchange capacity. The performance of the PIMs was investigated under various conditions such as percentage of carrier and initial dye concentration. With permeability and flux values of 0.1188 cm/min and 1.1913 mg cm/min, PIM produced with 18% w/w PVDF-co-HFP, 21% w/w B2EHP, 1% w/w DOP and 40% w/w THF and was able to achieve more than 97% of MG extraction. The experimental data were then fitted with a pseudo-second-order (PSO) model, and the calculated R2 value was ~0.99. This shows that the data has a good fit with the PSO model. PIM is a potential alternative technology in textile industry effluent treatment; however, the right formulation is crucial for developing a highly efficient membrane.

“…For example, Salima et al [ 60 ] used PIMs containing CTA as the base polymer, 2-nitrophenyl octyl ether as a plasticizer, and Aliquat 336 as a carrier for removing two types of acid dyes: red Bordeaux acid and yellow Erionyl from aqueous solution. To determine the optimal conditions for conducting the membrane extraction process, they analyzed the influence of such factors as the pH of the aqueous solution, the initial concentration of dyes in the feed solution and of Aliquat 336 in the membrane, and the stirring speed.…”

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.

The present study is interested in removal of a cationic dye gentian violet (GV) using a polystyrene membrane (PS) activated with oleic acid (OA). These innovative membranes were developed by using PS as the base polymer and OA as extractant. The best matrix obtained was characterized by using Fourier transform infrared spectroscopy (FTIR) and x‐ray diffraction (XRD), and then applied in the extraction of a cationic GV dye. The effects of an extraction ratio (OA/PS) in the PS‐AO matrix, initial GV dye concentration ([GV]0), and pH of the solution were studied in a batch reactor. The thermodynamic parameters (, , and ) have been calculated. Therefore, the GV extraction onto the PS‐OA matrix is an exothermic and spontaneous process. In addition, the slop method confirms that the chemical formula of the extracted OA‐GV complex is GV‐RHR. The central composite design (CCD) was used to determine the conditions of each experimental run, and extraction optimization was achieved using response surface methodology (RSM). The results showed that the quadratic regression model was statistically significant (0.9994), and the parameters studied had a profound effect on the extraction efficiency. The optimum GV extraction efficiency of 99% was achieved at an extractant ratio of 1, pH of 8, and [GV]0 of 10 mg L−1. The findings of the current study reveal that PS‐AO matrix is an advantageous and effective membrane for the extraction of GV from aqueous solutions, both environmentally and economically, it can be regenerated and used up to five times.
