Synthesis and characterization of allyl mannitol cross-linker based novel hydrogel for capturing of toxic metal ions from aqueous solution

Separation Science and Technology, Journal Year: 2024, Volume and Issue: unknown, P. 1 - 20

Published: Oct. 9, 2024

Three grades of allyl-mannitol cross-linker-based hydrogel (AMCLHs hydrogel) have been synthesized with the help acrylic acid and acrylamide monomers using a free radical co-polymerization technique. The three prepared AMCLHs referred to as AMCLHs-1, AMCLHs-2, AMCLHs-3, respectively. hydrogels characterized by several analytical techniques viz. Fourier transform infrared (FTIR) spectroscopy, thermogravimetric (TG) analysis, point zero charge (ΔpHPZC), scanning electron microscope (SEM) utilized for elimination Cu2+ Co2+ ions from wastewater. properties hydrogels, i.e. swelling water retention ratio studied in distilled under optimized conditions. maximum best grade (AMCLHs-1) has found be 400.5 g/g 75.09% during 24 h. These findings indicate AMCLHs-1 remarkable capacity. metal ion removal efficiency aqueous solutions 96.6% 94.2% optimum experimental data fitted well Langmuir Freundlich adsorption models, revealing capacities 431.03 mg/g 414.93 ions, In addition, rate onto follows both Pseudo first second-order kinetic models. negative ΔG values that process occurs spontaneously, while positive ΔH suggest is exothermic nature. reusable exhibits high desorption 87.63% 85.21% even after fourth cycle. Overall, cost-effective adsorbent possesses significant potential heavy solutions.

Removal of copper and cobalt ions from aqueous solutions using starch‐xanthate based novel smart hydrogel via adsorption technique: Swelling, adsorption isotherm, and kinetic study

Journal of Applied Polymer Science, Journal Year: 2024, Volume and Issue: 141(44)

Published: Aug. 20, 2024

Abstract The concentration of harmful metal ions is growing globally, which raises the risk to both human and ecological health. use “adsorption” technique has been found be very effective, for removal toxic ions. Among other things, hydrogels as an adsorbent work effectively aquatic pollutants. newly designed potato starch‐xanthate (SX) based hydrogel (SX‐modified hydrogel) synthesized using a mixture acrylamide (AAm) acrylic acid (AA) monomers, with help free‐radical graft copolymerization technique. SX‐modified characterized by several analytical techniques, namely, UV–visible (UV–vis) spectroscopy, Fourier transform infrared (FTIR) gel permeation chromatography (GPC), thermogravimetric (TG) analysis, point zero charge (ΔpH PZC ) x‐ray diffraction (XRD) scanning electron microscope (SEM) analysis. main objective current remove Cu 2+ Co from wastewater well study swelling water retention properties hydrogel. ratio 312.31, 374.01, 410.20 g/g at optimum pH 10, temperature 35°C, time 675 min in gray wastewater, tap water, distilled respectively. maximum percentage 97.7% 94.2%, respectively, conditions. Langmuir isotherm model fits best experimental data, adsorption capacity 515.46 mg/g 483.09 ions, kinetic studies suggest that process governed second order rate constant 2.06 × 10 −4 g/(mg min) 1.79 negative Δ G values spontaneous nature. In addition, positive H support endothermic showed remarkable desorption efficiency 96.7% 92.5% reusability four consecutive adsorption–desorption cycles. It can concluded economical, easy, low energy consuming, significant potential treatment containing heavy
