“…However, due to the higher swelling capacity in KOH it shows that it's mostly used in hygiene. The ionic hydrogel is sensitive to ambient pH in acidic conditions, according to equilibrium swelling tests (Yahaya et al, 2021). The swelling emulated the degree of crosslinking of CMC hydrogel.…”

Hydrogels are three-dimensional crosslinked polymers with several uses in the administration and loading of drugs as well as the capacity to hold enormous amounts of water or biological fluids. Using carboxymethyl cellulose, N,N-dimethyl acrylamide (DMA), 2-acrylamido-2-methyl-1-propane sulphonic acid (AMPS), N,N-bisacrylamide (MBA) as a crosslinker, and potassium persulate (KPS) as an initiator, the CMC-g-poly(DMA-co-AMPS) was created. FTIR spectroscopy was used to characterize the CMC-g-poly(DMA-co-AMPS). In distilled water, KOH, and HCl, the CMC-g-poly(DMA-co-AMPS)'s swelling capability was assessed. CMC-g-poly(DMA-co-AMPS has the largest swelling ratio in KOH, followed by HCl, while pure water has the lowest swelling ratio. Various salt solutions (FeCl3.6H2O, CuCl2, and NaCl) were used at predetermined times in distilled water to test the effect of ionic strength on CMC-g-poly(DMA-co-AMPS). The swelling of CMC-g-poly(DMA-co-AMPS) increased with the increase in salt solution concentration, and the ionic strength of a solution is the measure of the concentration of ions in salt solutions. In salt solutions (CuCl2, NaCl, and FeCl3.6H2O), the maximal swelling ratio of CMC-g-poly(DMA-co-AMPS) is 10.5g, 10.0g, and 9.5g, respectively.

Wastewater from industries contributes significantly to pollution. Adsorption of acidic dye using by nanohybrid biopolymeric hydrogels has evolved as one of the viable techniques. Graphene oxide (GO)/chitosan (CS)–polyvinyl alcohol (PVA), GO/starch–PVA, and GO/agar–PVA hydrogels were synthesized. The results revealed that the following results are the ideal values: GO/CS–PVA: 3 pH (8.251 mg g−1), 0.05 g/50mL dosage (8.251 mg g−1), 90 min (8.251 mg g−1), 12 ppm dye concentration (8.251 mg g−1), and 30 °C (8.251 mg g−1); for GO/starch–PVA: 2 pH (7.437 mg g−1), 0.05 g/50 mL dosage (7.437 mg g−1), 90 min (7.437 mg g−1), 12 ppm dye concentration (7.437 mg g−1), and 30 °C (7.437 mg g−1); and for GO/agar–PVA; 3 pH (6.142 mg g−1), 0.05 g/50 mL dosage (6.142 mg g−1), 90 min (6.142 mg g−1), 12 ppm dye concentration (6.142 mg g−1), 30 °C (6.142 mg g−1). GO/CS–PVA outperformed the other hydrogels. The Langmuir model suited GO/CS–PVA data, while GO/starch–PVA and GO/agar–PVA hydrogels followed Freundlich isotherm models. The adsorption capacity data followed a pseudo-second-order model. Negative value of Gibbs free energy and enthalpy showed that the reactions were spontaneous and exothermic in nature. The presence of heavy metals, electrolytes, and detergents/surfactants affected the dye adsorption. Entropy changes positive values implied that randomness raised at the solid/solution contact. The desorption (60, 55, and 58%) of GO/CS–PVA, GO/starch–PVA, and GO/agar–PVA hydrogels was obtained using 0.5 N NaOH. Scanning electron microscope, X-ray diffraction, and Fourier transform infrared (FT-IR) were used for characterization.
