Synthesis, utilization, and recycling of graphene oxide-based nanohybrid biopolymeric hydrogels for purification of dye wastewater

AQUA - Water Infrastructure Ecosystems and Society, Journal Year: 2024, Volume and Issue: 73(6), P. 1228 - 1256

Published: May 10, 2024

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