“…Hydrogel films are superabsorbent by nature, and their manufacturing costs are far lower than synthetic polymers [13]. Hydrogels have a variety of applications including agriculture [14,15] chemical and biosensors [16], water purification, removal of oil and metal ions [17][18][19], and medical as well as in food packaging [20]. e creation of poly-ion complex hydrogels is a new way of generating bio-based polymers for food packaging.…”

In the current study, a guar-gum-based biodegradable hydrogel film was prepared using an initiator (potassium persulfate), crosslinker (N-N methyl bis acrylamide), and plasticizer (glycerol) for packaging of fruits and vegetables. The effect of independent variables (initiator, crosslinker, and plasticizer) on the biodegradation (% wt. loss), color difference (ΔE), hardness (N), swelling index (%), and transparency (%) of the film was studied using Box–Behnken design, random surface methodology (RSM). The results showed significant effects on all the abovementioned parameters, and it was observed that the developed model was accurate, with a prediction error of only −3.19 to 2.99%. The optimized formulation for the preparation of hydrogel film was 0.15% initiator, 0.02% crosslinker, and 2.88% plasticizer exhibiting satisfactory biodegradability, color difference, hardness, swelling index, and transparency. Results showed that a guar-gum-based biodegradable hydrogel film has adequate physical, optical, and biodegradable properties and can be successfully utilized in the food packaging industry.

“…The hydrogel adsorbents synthesized from cellulose and its derivatives are an excellent choice for removing harmful contaminants from wastewater streams due to their adsorption efficiency, non-toxicity, renewability, functionality, etc. [197][198][199][200] The electrostatic interaction between the hydrogel and the pollutants is the dominant mechanism for wastewater treatment (Fig. 13).…”

“…Table 2 demonstrates the gap in the literature based on the recently published review articles that are closely aligned to the proposed topic. A recently published book chapter has covered a few parts of the topic; however, it lacks the critical content, such as different adsorption mechanisms required to develop a comprehensive understanding of the topic [ 56 ]. This review is systematically designed to include critical information on the topic such as the development of CBHs for the dye and heavy metal adsorption from industrial effluent, adsorption mechanism, and factors affecting the adsorption capacity along with future outlook.…”

Finding affordable and environment-friendly options to decontaminate wastewater generated with heavy metals and dyes to prevent the depletion of accessible freshwater resources is one of the indispensable challenges of the 21st century. Adsorption is yet to be the most effective and low-cost wastewater treatment method used for the removal of pollutants from wastewater, while naturally derived adsorbent materials have garnered tremendous attention. One promising example of such adsorbents is hydrogels (HGs), which constitute a three-dimensional polymeric network of hydrophilic groups that is highly capable of adsorbing a large quantity of metal ions and dyes from wastewater. Although HGs can also be prepared from synthetic polymers, natural polymers have improved environmental benignity. Recently, cellulose-based hydrogels (CBHs) have been extensively studied owing to their high abundance, biodegradability, non-toxicity, and excellent adsorption capacity. This review emphasizes different CBH adsorbents in the context of dyes and heavy metals removal from wastewater following diverse synthesis techniques and adsorption mechanisms. This study also summarizes various process parameters necessary to optimize adsorption capacity followed by future research directions.
