Nowadays, pollution has become the main bottleneck towards sustainable technological development due to its detrimental implications in human and ecosystem health. Removal of pollutants from surrounding environment is a hot research area worldwide; diverse technologies materials are being continuously developed. To this end, bio-based composite hydrogels as sorbents have received extensive attention recent years because advantages such high adsorptive capacity, controllable mechanical properties, cost effectiveness, potential for upscaling continuous flow installations. In review, we aim provide an up-to-date analysis literature on accomplishments design polysaccharide-based removal heavy metal ions, dyes, oxyanions wastewater. The correlation between constituent polysaccharides (chitosan, cellulose, alginate, starch, pectin, pullulan, xanthan, salecan, etc.), engineered composition (presence other organic and/or inorganic components), sorption conditions performance addressed will be carefully scrutinized. Particular paid sustainability aspects selected studies, particularly selectivity reusability, well their use fixed-bed columns real wastewater applications.

Abstract Hydrogel composites comprised of N,O carboxymethyl chitosan crosslinked with different weight ratios acrylic acid and fabricated nanoclay particle were prepared via gamma irradiation at 25 kGy dose. The coded as CsAA 1 Cl, 2 Cl 3 based on the ratio to derivative. claimed hydrogels characterized by FTIR, TGA XRD. data implied that incorporation clay nanoparticles enhanced thermal stability composites; decomposition temperature increased up 500 °C for Cl. Three AFM outcomes used compare surface features samples; topography, height roughness. topography reveals particles incorporated in are intercalated exfoliated. Then, optimized sorbent (CsAA Cl) was investigated green sorbents chromium (VI) lead (II). revealed displayed maximum removal performance towards both efficiencies 125 mg/g 205 respectively optimum application conditions within 90 min only. Also, it found pH value 9 8 lead. proved adsorption cations followed pseudo-first order kinetic model. showed acceptable metal uptake capacity three successive cycles. Graphical
