The synthesized hydrogel was optimized to achieve the best concentrations of the adsorbent constituents, i.e., 1.55% guar gum, 1.46% NC, and 0.84% borax for achieving the maximum swelling index (SI, 3741.42%) and higher adsorption capacity (<i>q</i>_e, 24.05 mg g^-1). 98.8% of dye <i>q</i>_e was achieved at optimal conditions of pH 8 within 30 min at 30 °C. Adsorption isotherms and kinetics investigations showed good correlation with the Freundlich adsorption isotherm model (<i>R</i>² > 0.9889; Δ<i>G</i>° = -4.71; Δ<i>H</i>° = -12.30; Δ<i>S</i>° = -0.025) as well as the pseudo-second-order kinACS omega8904-8922https://www.ebi.ac.uk/biostudies/studies/S-EPMC10905691biostudies-literatureNanocellulose-Based Ecofriendly Nanocomposite for Effective Wastewater Remediation: A Study on Its Process Optimization, Improved Swelling, Adsorption, and Thermal and Mechanical Behavior.PMC10905691Goswami SAnamikaSareen DRana HfalseNanocellulose-Based Ecofriendly Nanocomposite for Effective Wastewater Remediation: A Study on Its Process Optimization, Improved Swelling, Adsorption, and Thermal and Mechanical Behavior.A nanocellulose (NC)-based cross-linked adsorbent has been employed herein for the removal of dye pollutants (e.g., methylene blue) from the textile industry.
