“…The water selectivity of hydrophilic membranes may be improved by reducing swelling of the membranes. Swelling of the membranes may be reduced by crosslinking, 11,20 blending with less water swelling polymer, 3 copolymerization of two functional monomers, 1,9,13 allowing polymerization of one hydrophilic monomer in the matrix of a polymer to produce IPN type polymer 21 and using composite membranes. 10,12,14,16,19,22 These modifications improve water selectivity of the resulting membranes to some extent but flux is not increased because of the dense network structure formed by most of these modifications.…”

BACKGROUND: Low energy and less expensive membrane based separation of acetic acid-water mixtures would be a better alternative to conventional separation processes. However, suitable acid resistant membranes are still lacking. Thus, the objective of the present study was to develop mixed matrix membrane (MMM) which would allow high flux and water selectivity over a wide range of feed concentrations of acid in water.

“…The broad band from 1203 cm −1 to 1036 cm −1 are due to absorption of sugar ring of CMC . The band at 2950 cm −1 corresponds to C—H stretching of alkane of the hydrogels . The N—H stretching of AM is observed at around 3320 cm −1 in the IPNs.…”

Semi‐interpenetrating network (IPN) hydrogels were synthesized by free radical copolymerization of acrylamide (AM) and hydroxyethyl methacrylate (HEMA) in aqueous solution of sodium carboxy methyl cellulose (CMC). The hydrogels were crosslinked with N,N′‐methylene bisacrylamide (NMBA). Hydrogel was also synthesized from copolymerisation of AM and HEMA. This was designated as PAMHEMA. All of these hydrogels were characterized by Fourier transforms infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), X‐ray diffraction (XRD), mechanical properties, and equilibrium swelling in deionized water. These hydrogels were used for adsorption of two important textile dyes, i.e., basic fuchsin and methyl violet from water at different experimental conditions. These hydrogels were found to show high removal% and adsorption of these two dyes from water for both low and high feed concentration range. Experimental dye adsorption data were fitted to five kinetic and seven adsorption model equations with non‐linear fittings. The experimental data were observed to fit well to most of these model equations because of non‐linear fitting. POLYM. ENG. SCI., 53:2439–2453, 2013. ©2013 Society of Plastics Engineers

“…The objective of chemically modifying the PVOH matrix with poly (acrylic acid -co-acrylamide) was twofold. By incorporation of poly (acrylic acid -co-acrylamide) in PVOH matrix, the crystallinity of PVOH would be reduced to give enhanced water permeability [8].…”
