“…Interestingly, all three hydrogels had a similar swelling ability in saline solution. Furthermore, they displayed anomalous swelling behavior similar to the overshooting effect . The overshooting effect describes the phenomenon where hydrogels first swell to a maximum, and gradually de‐swell to a lower equilibrium value.…”

“…As the pH increased, the water absorption increased as well due to the generation of anionic COO − groups within the hydrogel. These charged functional groups repelled each other via electrostatic forces, thus allowing the network to expand and absorb water . Itaconic acid is a dicarboxylic acid with pK a values of 3.84 and 5.45 .…”

“…Monomers such as acrylic acid, acrylamide, and acrylonitrile have been used to this end. The graft copolymers have been used to make hydrogels, flocculants, and ion exchangers . Starch‐based hydrogels have the potential to be used as adsorbent materials for the treatment of wastewater contaminated with heavy metals.…”

Bio‐based hydrogels destined for use as low cost renewable biosorbents are synthesized. The impact of the two components of starch, amylose, and amylopectin, on the properties of the hydrogels is assessed. Hydrogels are synthesized by solution based graft copolymerization of itaconic acid monomers on a corn starch backbone in the presence of an acrylamide crosslinker and the potassium persulfate/sodium bisulfite redox initiator pair. Three types of corn starch are used: normal corn starch, waxy starch, and high amylose starch. The amylose:amylopectin ratios are: 27:73 for normal starch (NS), 70:30 for high amylose starch (HAS), and 0:100 for waxy starch (WS). Swelling tests performed in a variety of solutions show no significant differences in swelling capacity among the hydrogels. The hydrogels also perform similarly in copper adsorption tests. Overall, these results indicate that native corn starch is as effective as amylopectin and amylose‐rich starch.

“…IA HGs and their esters have also been proved to be effective for metal ions adsorption. HGs that contain itaconic acid effectively adsorb Pb 2+ , Cd 2+ , Cu 2+ , and Zn 2+ ions . In addition, poly(octadecyl diitaconate) has been used as filler material for preconcentration of cadmium, showing to be a good sorbent material for Cd 2+ .…”

Poly(acrylamide‐co‐itaconic acid) (AAm/IA) and poly(acrylamide‐co‐monomethoxyethyl itaconate) (AAm/MEI) hydrogels (HGs) synthesized at different molar ratios were used to study the adsorption of some metal ions as Cu2+, Ni2+, Pb2+, Cd2+, and Fe3+ in aqueous solutions at different concentration: 10, 50, 100, 500, and 1000 mg L−1. Statistical analysis was performed and the effect of the metal ion, ion concentration, and hydrogel (HG) composition, on adsorption and adsorption efficiency, was evaluated for both HGs studied (AAm/IA and AAm/MEI) and each factor gave rise to significant differences (P ≤ 0.05). The adsorption depends on the type of ion, its concentration, and also influenced by the type and composition of the HGs. For each system the adsorption efficiencies for all ions were similar with exception of Fe3+, which showed the highest adsorption efficiency in AAm/MEI HG, but the less for the AAm/IA. For both systems, the maximum adsorption efficiency was observed when the molar ratio AAm/IA or AAm/MEI is 80/20. When the adsorption was carried out with individual ions, AAm/MEI HG was more efficient than AAm/IA. For a multielement sample of Cu2+, Ni2+, Pb2+, and Cd2+, both HGs could adsorb all the ions and their behavioral trend was the same in both cases, in which the adsorption efficiency was Pb2+ > Cu2+ > Cd2+ > Ni2+. The results of the statistical analysis evidence the advantage of its use in this type of studies. © 2018 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2019, 136, 46999

Since organic dyes are poorly biodegradable and completely soluble, they are difficult to be efficiently and rapidly removed. Therefore, a poly(itaconic acid)/ magnetite sepiolite composite (PIA/MSEP) is prepared via a simple and environmentally friendly approach. The resulting adsorbent is employed for adsorption of methylene blue (MB) and methyl violet (MV). Factors influencing dyes adsorption efficiency are systemically researched, such as pH, contact time, temperature, and initial concentration of dye. Under optimal experimental conditions, the adsorption behaviour is satisfactorily modelled by the Langmuir model, and the maximum adsorption capacity reaches 196.08 and 175.44 mg Á g −1 for MB and MV, respectively. Adsorption is a fast process, well represented by pseudo-second-order rate expression, and being the equilibrium reached as short as 30 minutes for both MB and MV. The thermodynamic parameters suggest a favourable, spontaneous, and endothermic process. Fast, kinetic, and convenient magnetic separation, and a high adsorption capacity, make PIA/MSEP composite an impressive adsorbent for adsorption of organic dyes.
