“…S=O of the sulfonic acid group, respectively [122,184,185]. For GO hybridized CS membrane, reaction between primary –NH 2 of CS with epoxy group of GO was identified from the increase in N–H bending, along with the weakening of primary –NH 2 peak at 1651 cm −1 [136,186,187,188]. Though, the authors have not reported the change in FTIR peak corresponding to the epoxy group of GO as a result of reaction with primary –NH 2 , such reaction was confirmed from the increased intensity of C–N specific deconvoluted C1s spectra for the GO hybridized membrane.…”

For the fulfilment of increasing global demand and associated challenges related to the supply of clean-and-safe water, PV has been considered as one of the most attractive and promising areas in desalinating salty-water of varied salinities. In pervaporative desalination, the sustainability, endurance, and structural features of membrane, along with operating parameters, play the dominant roles and impart paramount impact in governing the overall PV efficiency. Indeed, polymeric- and organic-membranes suffer from several drawbacks, including inferior structural stability and durability, whereas the fabrication of purely inorganic membranes is complicated and costly. Therefore, recent development on the high-performance and cost-friendly PV membrane is mostly concentrated on synthesizing composite- and NCP-membranes possessing the advantages of both organic- and inorganic-membranes. This review reflects the insights into the physicochemical properties and fabrication approaches of different classes of PV membranes, especially composite- and NCP-membranes. The mass transport mechanisms interrelated to the specialized structural features have been discussed. Additionally, the performance potential and application prospects of these membranes in a wide spectrum of desalination and wastewater treatment have been elaborated. Finally, the challenges and future perspectives have been identified in developing and scaling up different high-performance membranes suitable for broader commercial applications.

“…In this context, it is reported that both TS and EAB are severely affected by the methods and several input variables, including different relative mole ratios of all ingredients and the respective nature, vulcanization-/crosslinking-/curing-agent, time and temperature, of membrane synthesis [ 70 ]. Indeed, the exact balance between TS and EAB can be obtained by implementing response surface methodology (RSM), a frequently used statistical technique, via performing minimum number of experiments/runs [ 370 ]. In fact, the use of RSM to obtain the amounts of ingredients, like the crosslinker, filler and accelerator, for synthesizing accelerated sulfur vulcanized and carbon nano particle filled natural rubber membrane has been reported by Karmakar et al [ 371 ], in which a substantial variation of both TS and EAB has been observed with the little change in such amounts.…”

Pervaporation (PV) has been considered as one of the most active and promising areas in membrane technologies in separating close boiling or azeotropic liquid mixtures, heat sensitive biomaterials, water or organics from its mixtures that are indispensable constituents for various important chemical and bio-separations. In the PV process, the membrane plays the most pivotal role and is of paramount importance in governing the overall efficiency. This article evaluates and collaborates the current research towards the development of next generation nanomaterials (NMs) and embedded polymeric membranes with regard to its synthesis, fabrication and application strategies, challenges and future prospects.

“…In fact, such industries use more than 10 000 dissimilar nonbiodegradable aromatic synthetic dyes for conquering, intensifying, and maintaining the color of products, of which around 15 wt % of these are discharged as wastes. 13 Among several popular synthetic dyes, safranine (SF) is one of the most extensively used dyes for dyeing natural fibers. SF is frequently used for dyeing wool, silk, and acrylic fibers and leather.…”

“…Response surface methodology (RSM) is widely used for analyzing synergistic effects of process variables on response(s) to physical/chemical studies through the minimum number of experimental runs. However, few studies have been devoted for RSM-based optimization of operational variables during adsorption for attaining the maximum adsorption capacity (AC). , In the present study, RSM has been employed for systematic multistage optimization of variables for synthesis of a hydrogel possessing the maximum equilibrium swelling ratio (ESR).…”

Pectin- g -(sodium acrylate- co -3-( N -isopropylacrylamido) sodium propanoate- co - N -isopropylacrylamide) interpenetrating polymer networks (PANIPNs) were synthesized through systematic multistage optimization of equilibrium swelling ratio by response surface methodology for individual and/or synergistic removal(s) of cationic safranine (SF), anionic methyl orange, and M(II/III), such as Hg(II), Cd(II), and Cr(III). The relative effects of copolymer compositions on ligand-selective adsorption, strong/weak H-bonds, thermal stabilities, crystallinity, surface properties, swelling abilities, cross-link densities, network parameters, hydrophilic–hydrophobic characteristics, and adsorption capacities (ACs) were measured through extensive microstructural analyses of adsorbed and/or unadsorbed PANIPN41 and PANIPN21 bearing sodium acrylate and N -isopropylacrylamide (SA/NIPAm) in 4:1 and 2:1 ratios, respectively, using Fourier transform infrared, 1 H and 13 C NMR, X-ray photoelectron spectroscopy, thermogravimetric analysis, differential scanning calorimetry, X-ray diffraction, scanning electron microscopy, and energy dispersive X-ray spectroscopy, along with measuring lower critical solution temperature, % gel content (% GC), % −COOH, and pH PZC . Extensive UV–vis measurements were carried out at varying copolymer compositions, initial pH (pH i ), and dyes, interpreted considering monomer–dimer and azonium–ammonium equilibrium of dye, dye–dye complexation, ligand-selective PANIPNs–dye adduct formation, π–π stacking interactions, and orientation effect of dyes. Thermodynamically feasible chemisorption processes showed the maximum ACs of 127.61, 96.78, 103.36, and 99.41 mg g –1 for SF, Hg(II), Cd(II), and Cr(III), respectively, under optimum conditions.
