“…One possibility investigated is associated with natural polymers, especially polysaccharides (chitin, starch, chitosan, cellulose, pectine, alginate, agarose, etc. ), which are used because they offer several advantages: renewability, high abundance, biodegradability, eco-friendliness, economic feasibility, and high adsorption capacity [ 2 , 3 , 4 ]. Moreover, through chemical reactions, polysaccharides can produce macromolecular superstructures (nanoparticles, fibers, membranes, films, beads, and gels) that can be used as biosorbents for various pollutants’ removal from aqueous effluents.…”
