“…The pseudo-first and pseudo-second-order kinetic parameter values for MO adsorption are presented in Table 4 . The correlation coefficient criterion (highest value of R 2 ) was used to describe the most suitable kinetic adsorption model [ 52 ]. According to the described criteria, MO adsorption for hydrogel Hy01 conforms to the pseudo-second-order kinetic model with an R 2 value greater than 0.9733 (see Figure 11 ).…”

Bio-based hydrogels that adsorb contaminant dyes, such as methyl orange (MO), were synthesized and characterized in this study. The synthesis of poly([2-(acryloyloxy)ethyl] trimethylammonium chloride) and poly(ClAETA) hydrogels containing cellulose nanofibrillated (CNF) was carried out by free-radical polymerization based on a factorial experimental design. The hydrogels were characterized by Fourier transformed infrared spectroscopy, scanning electron microscopy, and thermogravimetry. Adsorption studies of MO were performed, varying time, pH, CNF concentration, initial dye concentration and reuse cycles, determining that when the hydrogels were reinforced with CNF, the dye removal values reached approximately 96%, and that the material was stable when the maximum swelling capacity was attained. The maximum amount of MO retained per gram of hydrogel (q = mg MO g−1) was 1379.0 mg g−1 for the hydrogel containing 1% (w w−1) CNF. Furthermore, it was found that the absorption capacity of MO dye can be improved when the medium pH tends to be neutral (pH = 7.64). The obtained hydrogels can be applicable for the treatment of water containing anionic dyes.

“…Methylene blue dye removal by IA, acrylic acid, and 2–hydroxyethyl methacrylate obtained through copolymerization was between 197–260 mg/g. Although the reusability of this hydrogel was only applicable for three successive cycles, it is still a prospective adsorbent for the withdrawal of cationic dyes from water solutions [ 129 ].…”

Intense research has been conducted to produce environmentally friendly biopolymers obtained from renewable feedstock to substitute fossil-based materials. This is an essential aspect for implementing the circular bioeconomy strategy, expressly declared by the European Commission in 2018 in terms of “repair, reuse, and recycling”. Competent carbon-neutral alternatives are renewable biomass waste for chemical element production, with proficient recyclability properties. Itaconic acid (IA) is a valuable platform chemical integrated into the first 12 building block compounds the achievement of which is feasible from renewable biomass or bio-wastes (agricultural, food by-products, or municipal organic waste) in conformity with the US Department of Energy. IA is primarily obtained through fermentation with Aspergillus terreus, but nowadays several microorganisms are genetically engineered to produce this organic acid in high quantities and on different substrates. Given its trifunctional structure, IA allows the synthesis of various novel biopolymers, such as drug carriers, intelligent food packaging, antimicrobial biopolymers, hydrogels in water treatment and analysis, and superabsorbent polymers binding agents. In addition, IA shows antimicrobial, anti-inflammatory, and antitumor activity. Moreover, this biopolymer retains qualities like environmental effectiveness, biocompatibility, and sustainability. This manuscript aims to address the production of IA from renewable sources to create a sustainable circular economy in the future. Moreover, being an essential monomer in polymer synthesis it possesses a continuous provocation in the biopolymer chemistry domain and technologies, as defined in the present review.

“…However, the crosslinking conditions of natural organic adsorbents are very harsh, and crosslinking signicantly reduces the exibility of molecular chains and the mobility and activity of adsorption sites; thus, crosslinking can weaken the adsorption ability of organic adsorbents; still, a high degree of crosslinking is necessary to ensure that the chains are strong. 21 At present, articial organic adsorbents, such as 2-hydroxyethyl methacrylate (HEMA) 22 and polyvinyl butyral (PVB), 23 have been widely applied in the wastewater treatment eld because these organic adsorbents contain many active groups and are easily modied (crosslinking, graing, etc.). Polyethylenimine (PEI) with good reactivity and chelating ability has been reported to be a potential candidate in the wastewater treatment eld owing to the existence of primary and secondary amine groups.…”
