AB  - One of today's imperatives is the effective removal of pollutants from the biosphere, particularly from natural and wastewater sources. The removal of metal ions from solutions has long been a goal of numerous investigations, and hydrogels have been utilized as sorbent materials for this purpose. [1,2] This research was performed in order to create a new class of poly(oligo(propylene glycol methacrylate)/oligo(ethylene glycol methacrylate))/acid), abbreviated as p(OPGMA/OEGMA/acid), temperature-responsive copolymeric hydrogels and to analyze the influence of different acids on the volume phase transition temperature (VPTT) of the obtained hydrogels and on the efficiency of Mn+2 removal from the water. In this work, three acids were used: itaconic (IA), acrylic (AA), and methacrylate (MA), which were incorporated into the composition of the hydrogel in the monomer feed ratio OPGMA/OEGMA/acid of 95:2:3. Henceforth, the obtained hydrogels p(OPGMA/OEGMA/acid) were synthesized for the first time by γ-irradiation polymerization and crosslinking of monomers from a water/ethanol solution. The hydrogels were put through swelling analysis and testing as potential sorbents once the high level of gel content was confirmed. Taking into account the size of the metal ions, their concentration in the solution, and the porosity of the gel, the results show that hydrogels can be employed to remove manganese ions from solutions.

AB  - For many years now, thermally actuated hydrogels have been the ones most studied and employed in the field of polymeric biomaterials. The monomers, N-isopropyl acrylamide (NiPAM), and oligo(propylene glycol) methacrylate (OPGMA) were selected based on the sharp temperature response of their corresponding hydrogels in a known range of temperatures.1,2 This research was performed in order to create a new class of P(NiPAM/OPGMA) temperature-responsive hydrogels, and to analyze the influence of different content of monomers on the volume phase transition temperature (VPTT) of the obtained hydrogels. One of the objectives of this study was to provide insight into the effects of applied radiation dose on the swelling and mechanical properties of the hydrogels.  In further work, P(NiPAM/OPGMA) hydrogels were synthesized for the first time by γradiation crosslinking of monomers from water/ethanol solution. After the high sol-gel conversion was established, xerogels were subjected to swelling analysis and tested for the mechanism of water diffusion within the hydrogels. The obtained results indicated that new hydrogels based on NiPAM and OPGMA show promising potential for water treatment application due to the relatively high swelling degree of hydrogels and the ability to combine their VPTT close to annual river water temperatures in Serbia.
