A Comprehensive Review of Polysaccharide-Based Hydrogels as Promising Biomaterials

Polymers, Год журнала: 2023, Номер 15(13), С. 2908 - 2908

Опубликована: Июнь 30, 2023

Polysaccharides have emerged as a promising material for hydrogel preparation due to their biocompatibility, biodegradability, and low cost. This review focuses on polysaccharide-based hydrogels’ synthesis, characterization, applications. The various synthetic methods used prepare hydrogels are discussed. characterization techniques also highlighted evaluate the physical chemical properties of hydrogels. Finally, applications SAPs in fields discussed, along with potential benefits limitations. Due environmental concerns, this shows growing interest developing bio-sourced made from natural materials such polysaccharides. many beneficial properties, including good mechanical morphological thermal stability, non-toxicity, abundance, economic viability, swelling ability. However, some challenges remain be overcome, limiting formulation complexity establishing general protocol calculating water absorption retention capacity. Furthermore, development requires multidisciplinary approach research should focus improving modification, well exploring Biocompatibility, biodegradation, regulatory approval pathway carefully evaluated ensure safety efficacy.

The objective of this study is to find optimum preparation conditions in converting teak wood waste into activated carbon (TWAC) and evaluate its performance adsorbing cationic dye methylene blue (MB). TWAC was produced via physiochemical activation (potassium hydroxide, KOH chemical treatment, dioxide, CO2 gasification) heated through microwave irradiation technique. With the aid response surface methodology (RSM), optimized successfully synthesized at radiation power, time, impregnation ratio (IR) 366 W, 5.30 min, 1.15 g/g, respectively. These with MB adsorption uptakes 66.69 mg/g a yield 38.23%. Characteristics terms BET area, mesopores total pore volume, average diameter were determined be 1345.25 m2/g, 878.63 0.6140 cm3/g, 2.85 nm, Isotherm studies divulged that MB-TWAC system followed Langmuir model maximum monolayer capacity 567.52 mg/g. In kinetic studies, fit pseudo-second order best whereas Boyd plot confirmed process controlled by film diffusion mechanism. Thermodynamic parameters enthalpy change, ΔH°, entropy ΔS°, Gibbs free energy, ΔG° Arrhenius Ea calculated −4.06 kJ/mol, 0.06 kJ/mol.K, –22.69 kJ/mol 16.03 heating methods employed succeeded produce excellent removing dye. also regenerated for 5 cycles
