“…However, there have been significant concerns about heavy metal nanoparticles entry into water due to the use of some nanomaterials [ 10 , 11 ]. Recently, polyvinyl alcohol (PVA)-based hydrogel materials have also been used as efficient dye absorbers [ 12 , 13 , 14 , 15 , 16 ]. Mok et al prepared PVA hydrogel as an agent to remove dye from wastewater using methylene blue (MB) in aqueous solution [ 16 ].…”

“…Glutaraldehyde (GA) was used as a crosslinking agent and the hydrogel was characterized in terms of morphology, swelling, and adsorption. It was found that GA content and solution pH have a considerable effect on the adsorption capacity of PVA hydrogel [ 16 ]. In a separate study [ 17 ], Papancea et al examined PVA-scleroglucan, PVA-zein, and PVA-cellulose in combination with different types of dye such as MB, crystal violet (CV), and Congo red (CR) [ 17 ].…”

Polyvinyl Alcohol/Calcium Carbonate Nanocomposites as Efficient and Cost-Effective Cationic Dye Adsorbents

et al. 2020

A novel polyvinyl alcohol (PVA)/calcium carbonate-based double-layer cationic dye adsorbent was developed. Polyvinyl alcohol (50 wt %) and calcium carbonate (50 wt %) were used together with borax as a cross-linking agent. The nanocomposite was prepared using only water, without the need for any toxic solvent or hazardous chemical. The final samples were obtained by the solvent casting method. The nanocomposite adsorbent was characterized using a Fourier transform infrared (FTIR) spectroscope and a scanning electron microscope (SEM). The adsorption performance on two cationic dyes, i.e., methylene blue and safranin was studied. Dye adsorption was quantified by measuring the nanocomposite swelling, contact time, and dye concentration. Pseudo first-order and pseudo second-order kinetic models as well as intraparticle diffusion model were used to model the adsorption kinetics. Moreover, the isotherm dye adsorption was investigated by Langmuir and Freundlich models. The results revealed that the developed nanocomposite has relatively high adsorption efficiency and short adsorption time and retains its performance after several successive absorption–desorption processes. The results also showed that the pseudo-second-order model best describes the adsorption kinetics, and the Freundlich isotherm model has a better compatibility with the experimental data. Finally, an adsorption mechanism was proposed for the dye removal process. The developed PVA/CaCO3 nanocomposite can be potentially used for efficient dye removal in wastewater treatments.

“…Hydrogen bonding between PVA chains is often responsible for the semicrystalline nature of this polymer [8]. PVA has good water solubility, thermal stability, corrosion resistance, and optical transmission [9]. Different morphologies of PVA have also proven useful for pharmaceutical and biomedical characteristics.…”

Poly(vinyl alcohol) (PVA) has been considered as an important commercial synthetic thermoplastic polymer. PVA is a low cost, reasonably processable, optically transmitting, heat stable, and mechanically robust plastic. PVA-based nanomaterials usually comprise of the nanocomposites (PVA/graphene, PVA/carbon nanotube, PVA/nanodiamond, PVA/metal nanoparticle) and nanofibers. The structural, optical, mechanical, and electrical properties of the PVA-based nanomaterials have been enhanced with nanofiller addition or nanostructuring. This review offers fundamentals and advanced aspects of poly(vinyl alcohol) and the derived nanomaterials. It highlights recent advances in PVA nanocomposites and nanofibers for potential applications. The PVA-based nanomaterials have been successfully employed in fuel cells, sensors, batteries, membranes, electronics, and drug delivery relevances. The challenges and opportunities to strengthen the research fields of PVA-based nanomaterials have also been presented.

“…To this end, a variety of adsorbents such as carbon‐based materials, layered double hydroxides, natural materials, agricultural and industrial waste‐based materials, metal‐organic frameworks, polymers etc was applied for removing dyestuffs from aquatic environments . Polymeric sorbents are of particular interest because they offer noteworthy features such as the tailoring of physico‐chemical properties (molecular weight, composition, porosity, functionality), ease of handling and possibility of regeneration / reuse. A series of vibrant characteristics of phenolic resins, such as cost effective synthesis, macromolecular three‐dimensional structure, good stability in the environment and easy processibility, make them suitable for immense applications in different kinds of areas, as reported by many researchers.…”

The hazardous consequences of azo dye organics on the environment and human health motivate the development of new sorbent materials for their elimination from wastewater. The purpose of this work is to prepare pyridine‐rich novolac resin‐based network material 1 as effective adsorbent for the removal of azo dye pollutants, methyl orange (MO), orange‐II (OII) and orange‐G (OG) azo dyes from aqueous solution at a wide range of pH (acidic‐neutral‐basic conditions). Both electrostatic interaction and physical forces are suggested to be involved during adsorption of azo‐dyes onto tailored adsorbent. Besides, dye‐adsorbed 1 was effectively desorbed by dil H2SO4 and recycled, which is promising for its practical application in the treatment of dye contaminated water.
