“…Several studies on IPNs based on cellulose and polyacrylate/polymethacrylate [ 28 , 29 , 30 ] have shown that these materials have high toughness, high strength and good stability. These properties are not observed in the individual polymeric networks, because these ones are held together by physical interactions and permanent entanglements, such as hydrogen bonds.…”

The main objective of this work was the removal of eosin Y and green malachite from an aqueous medium by using a cellulose-based biodegradable interpenetrated network (IPN). The IPN was obtained by the sequenced synthesis method. In the first step, cellulose was crosslinked with epichlorohydrin (ECH). In the second step, the obtained gels were swollen in a reactive mixture solution, which was based on the monomers 2-hydroxyethyl methacrylate (HEMA) and 1,6- hexanediol diacrylate (HDDA). After this, swelling equilibrium was reached through the gels’ exposition to UV radiation. An infrared spectroscopy (FTIR) was used to analyze the bond stretching, which confirmed the IPN’s formation. The swelling kinetics in aqueous mediums with different pH values showed a high swelling at a basic pH value and a low response in neutral and acidic media. The IPNs showed an improvement in water uptake, compared to the networks based on PHEMA or cellulose. The IPN was used to remove dyes from the water. The results showed that a high percentage of green malachite was removed by the IPN in six minutes of contact time. The experimental results were confirmed by the docking/modeling method of the system (IPN/Dye). The different physical interactions between the IPN and the dyes’ molecules were investigated. The interactions of the hydrogen bonds with malachite green were stronger than those with eosin Y, which was in good agreement with the experimental results.

A novel chitosan (CTS)‐based double network Poly(2‐acrylaMido‐2‐Methyl‐1‐propanesulfonic acid)/Polyacrylamide/CTS hydrogel was synthesized by irradiation initiated. Laponite RD (RD) was used as both dopant and the cross‐linking agent. Then the fabricated hydrogel was applied as an efficient adsorbent to remove the methylene blue (MB) in an aqueous solution. This hydrogel has both high strength and good adsorption properties for MB. The results from Brunauer–Emmett–Teller method confirmed that the hydrogel has a large specific surface area (96 m2/g) and developed pore structure, which is available for the contact between the adsorbent and dye molecules. In the adsorption process, the RD provides plenty of negative charges as adsorption sites for MB molecules. The influence of pH, temperature, and adsorbent dose on the adsorption performance was investigated in detail. The experimental data fit well with the pseudo‐second‐order kinetic model and Langmuir isotherm. Besides, the mechanical strength of the hydrogel was also investigated in this work.

Environmental pollution with heavy metals, especially with hexavalent chromium, is a serious problem worldwide. Therefore, in this study, the synthesis, characterization, and application of a heavy metal bioadsorbent, CMCCHDIC, were carried out. Carboxymethylcellulose (CMC) was synthesized from corn stover and reacted with chitosan (CH) using N,N′‐diisopropylcarbodiimide (DIC) as a coupling reagent to obtain CMCCHDIC. CMC and CMCCHDIC were characterized by granulometric distribution of microparticles, scanning electron microscopy, Fourier transform infrared spectroscopy, thermogravimetric analysis, differential scanning calorimetry, and nuclear magnetic resonance. The ideal conditions for CMCCHDIC adsorption were determined, and 180 min of contact time, pH 2.5, and 293 K were observed to yield the best adsorption capacity. An increase in the adsorption capacity of CMCQDIC (qe = 115.78 ± 0.17 mg∙g−1) to 81.5% relative to that of pure CH (qe = 63.78 ± 0.48 mg∙g−1) was observed, and the reduction of solubility in acidic media comparing with CH, which favors the application of the bioadsorbent synthetized.
