In this study, poly-vinyl alcohol (PVA), acrylic acid (AAc), and poly-4-styrene sulphonic acid (PSSa) were copolymerized in different compositions using gamma irradiation to form the hydrogel. FTIR study showed that AAc act as a crosslinker for the formation of transparent hydrogel and optimization study affirmed that crosslinking density increased with the increase of AAc content. The swelling study revealed that hydrogel with 30% acrylic acid and 70% PSSa (PAC30PS70) exhibited the best swellin...

Abstract This work explored the potential of clinoptilolite, molybdenum sulphide (MoS2), and MoS2-clinoptilolite composite in lead (Pb) removal from aqueous medium and industrial mining wastewater. MoS2-clinoptilolite composite was successfully prepared by a hydrothermal method. The surface properties, structure, and composition of the synthesized composite and the parent compounds were analyzed by scanning electron microscopy, X-ray diffraction, energy-dispersive X-ray spectroscopy, and Fourier...

In this study, a sodium alginate poly(acrylic acid) (SA-poly(AA)) hydrogel and sodium alginate poly(acrylic acid)/zinc oxide (SA-poly(AA)/ZnO) hydrogel nanocomposite (HNC) was synthesized by in situ free-radical polymerization for the sequestration of toxic methylene blue (MB) dye from aqueous solution. The structural properties were analyzed using FTIR, XRD, SEM, TEM, TGA, and DMA The swelling analysis revealed that SA-poly(AA)/ZnO HNC exhibited high water uptake capacity. The kinetics, isother...

Abstract This paper describes the synthesis of hybrid hydrogels based on chondroitin sulfate (CS) and mesoporous silica (MCM-41). The combination of the CS network and surface-modified MCM-41 yields resilient hybrids with a high water absorption power and excellent capacity for the removal of methylene blue (MB). In this system, two types of solute transport mechanisms exist: absorption and adsorption. The effect of MCM-41 on the physical-chemical properties of the hydrogels was assessed over a ...

Abstract Industrialization increases use of dyes due to its high demand in paper, cosmetic, textile, leather and food industries. This in turn would increase wastewater generation from dye industrial activities. Various dyes and its structural compounds present in dye industrial wastewater have harmful effects on plants, animals and humans. Synthetic dyes are more resistant than natural dyes to physical and chemical methods for remediation which makes them more difficult to get decolorize. Micro...

Hydrogels, as a representative of soft and biocompatible material, have been widely used in biosensors, biomedical devices, soft robotics, and the marine industry. However, the ir-recoverability of hydrogels after dehydration, which will cause the loss of original mechanical, optical and wetting properties, has severely restricted their practical applications. At present, this critical challenge of maintaining hydrogels' accurate character has caused less attention. To address this, here we repo...

Abstract Removal of harmful dyes and inhabitation of bacterial growth is one of the outstanding priorities in both environmental and industrial applications. The recognition of the alarming industrial discharge and insufficiency of fresh water has prompted us to develop eco-friendly and sustainable dye adsorbent films. The present investigation reports the synthesis of melamine-formaldehyde (MF) and cross-linking of polyvinyl alcohol (PVA) with MF to develop biodegradable composite films. The PV...

Abstract Mesoporous silver-melamine (Ag-MA) nanocomposites were synthesized by controlled supramolecular self-assembly with various structural morphologies. It was discovered that the rod-like Ag-MA nanocomposites could present the larger Hg2+-enhanced catalysis by forming Ag-Hg alloys. Also, they could display large surface-to-volume area and high aqueous stability for the selective Hg2+ enrichment and absorption of Hg2+ ions by yielding the stable coordination complexes. A catalysis-based colo...
