“…Thus, grafting and cross-linking reactions with different reagents (acrylamide, acrylic acid, N-vinylimidazole, polyvinylamine, polyacrylate triethylenetetramine, 2-acrylamido-propanesulphonic acid) presented in different papers of the last decade concerning dye sorption by hydrogels based on CS enhance the adsorption and mechanical properties, as well as chemical stability, of the native polysaccharide. The same literature showed that the addition of various fillers (GO, MMT, phytic acid) or magnetic nanoparticles (Fe3O4) in the chemical structure of above-mentioned CS-based hydrogels augmented their dye sorption properties [50][51][52][53][54][55][56][57][58][59][60][61][62][63][64].…”

“…A composite hydrogel, Fe 3 O 4 @CS/p(AAM/NVIm), created by the incorporation of magnetic nanoparticles Fe 3 O 4 in CS grafted with AM and N-vinylimidazole (NVIm) was tested as adsorbent for MB dye (Figure 5) [53]. The composite hydrogel proved to be a promising recyclable, durable, robust, and efficient adsorbent for MB adsorption from wastewater.…”

Removal of contaminants from discharge water is vital and demands urgent assistance with the goal to keep clean water. Adsorption is one of the most common, efficient, and low-priced methods used in water treatment. Various polysaccharide-based gels have been used as efficient dye adsorbents from wastewater. This review summarizes cutting-edge research of the last decade of different hydrogels based on natural polysaccharides (chitin, chitosan, cellulose, starch, pullulan, and dextran) concerning their dye adsorption efficiency. Beyond their natural abundance, attributes of polysaccharides such as biocompatibility, biodegradability, and low cost make them not only efficient, but also environmentally sustainable candidates for water purification. The synthesis and dye removal performance together with the effect of diverse factors on gels retaining ability, kinetic, and isotherm models encountered in adsorption studies, are introduced. Thermodynamic parameters, sorbent recycling capacity along with conclusions and future prospects are also presented.

“…According to the literature, alginate–chitosan hydrogels can reach dye removal capacities of larger than 100 mg/g (sometimes even surpassing 2000 mg/g), while metal absorption capacity can range between 38 mg/g and more than 440 mg/g [ 161 ]. Recent studies in the field ( Table 5 ) have uncovered the potential of hydrogel-based magnetic composites for the removal of various organic dyes (e.g., reactive orange 16 [ 162 ], methylene blue [ 163 , 164 , 165 , 166 , 167 , 168 ], rhodamine B [ 166 ], methyl orange [ 168 ], and malachite green [ 168 ]) and environmentally harmful inorganic contaminants (e.g., Cd 2+ [ 169 ], Pb 2+ [ 168 , 170 , 171 ], Hg 2+ [ 168 ], Ni 2+ [ 168 ], Mn 2+ [ 171 ], Cu 2+ [ 171 ], Al, K, Se, Na, V, and S [ 158 ]).…”

Water contamination by harmful organic and inorganic compounds seriously burdens human health and aquatic life. A series of conventional water purification methods can be employed, yet they come with certain disadvantages, including resulting sludge or solid waste, incomplete treatment process, and high costs. To overcome these limitations, attention has been drawn to nanotechnology for fabricating better-performing adsorbents for contaminant removal. In particular, magnetic nanostructures hold promise for water decontamination applications, benefiting from easy removal from aqueous solutions. In this respect, numerous researchers worldwide have reported incorporating magnetic particles into many composite materials. Therefore, this review aims to present the newest advancements in the field of magnetic composites for water decontamination, describing the appealing properties of a series of base materials and including the results of the most recent studies. In more detail, carbon-, polymer-, hydrogel-, aerogel-, silica-, clay-, biochar-, metal–organic framework-, and covalent organic framework-based magnetic composites are overviewed, which have displayed promising adsorption capacity for industrial pollutants.

“…The adsorption kinetics and adsorption isotherm models for the adsorption removal of MB on the composite hydrogel could be satisfactorily described by the second-order kinetics and the Langmuir adsorption isotherm, respectively. The composite hydrogel was proposed as a promising recyclable, durable, robust, and efficient adsorbent for the adsorption of MB from wastewater [ 95 ]. A composite hydrogel loaded with ZnO nanoparticles was prepared by grafting acrylamide over CS and gelatin polymer chains in the presence of ammonium persulfate as the initiator and maleic acid as the crosslinker.…”
