“…Helical stacking of both compounds leads to the polymeric structures, which are stabilized through a combination of charge transfer interactions and Coulomb coupling. Another system that also involves electrostatic interactions consists of poly(acrylic acid-co-acylamide) hydrogels and the cationic dye methyl violet [43]. Different molar ratios of both monomers were employed and hydrogel synthesis occurred via gamma-irradiation.…”

Amongst functional macromolecules, the combination of polymers and dyes is a research field of great potential with regard to high-performance materials. Accordingly, colored polymers have become increasingly important as materials for miscellaneous technical applications in recent years while also being a major part of everyday life. For instance, dye-containing polymers are nowadays widely applied in medicine, painting industries, analytics and gas separation processes. Since these applications are obviously connected to the dye's nature, which is incorporated into the corresponding polymers, the affinity of certain polymers to dyes is exploited in wastewater work-ups after (textile) dyeing procedures. In this review, we wish to point out the great importance of dye-containing polymers, with a comprehensive scope and a focus on azo, triphenylmethane, indigoid, perylene and anthraquinone dyes. Since a large number of synthetic approaches towards the preparation of such materials can be found in the literature, an elaborated overview of different preparation techniques is given as well.

“…In recent years research on HSA have been intensively focused on some types of basic materials such as acrylic acid (AA) and acrylamide (AAM) monomers and its copolymers [6][7][8]. However, the disadvantage of HSA based on monomers/polymers synthetic is not biodegradable which will cause environmental problems.…”

“…In fact, it is known that charged hydrogels are able to adsorb effectively from water oppositely charged organic and inorganic pollutants. Thus, numerous studies have been devoted to the adsorption of cationic dyes, used as model pollutants, by anionic hydrogels (Jeon et al, 2008;Paulino et al, 2006;Solpan et al, 2003;Tang et al, 2009) containing weakly acidic or strongly charged groups.…”

Poly(sodium acrylate) hydrogels as potential pH-sensitive sorbents for the removal of model organic and inorganic pollutants from water

Anionic poly(sodium acrylate), PANa, hydrogels bearing negatively charged -COO -groups were used as sorbents for the removal of colored organic or inorganic model pollutants, namely Crystal Violet and Cu 2+, from water. It was found that PANa hydrogels adsorb stronger Cu 2+ ions than Crystal Violet, as a consequence of the formation of coordination complexes between the hydrogel and the metal ions, while just electrostatic interactions are the major driving forces for Crystal Violet. Furthermore, the influence of pH, i.e. the neutralization degree i of the hydrogel, on its adsorption efficiency was investigated. It is shown that the adsorption of Cu 2+ ions follows stoichiometry, namely one metal ion per two carboxylate anions. On the contrary, the adsorption of Crystal Violet is much lower than the charged stoichiometry.
