Summary: The gamma radiation technique is used to prepare pure hydrogels, which are essential in various fields. This study focuses on the preparation and characterization of DMAA-AMPSA superabsorbent hydrogel using gamma radiation and determining the optimal dose. The equilibrium swelling increases with increasing radiation dose, reaching a maximum of 26,324.9% at 10 kGy. The characterization techniques confirm the formation of the co-polymer and the thermal stability of the gel.

Summary: The introduction of two-dimensional montmorillonite nanosheets into carboxymethyl cellulose-based hydrogel has significantly improved its adsorption rate and capacity, leading to efficient removal of methylene blue. The enhanced performance and structural stability are likely attributed to the presence of nanosheets and increased porosity in the hydrogel structure.

Summary: An eco-friendly superabsorbent polymer (SAP) was prepared by grafting 2-acrylamido-2-methyl-1-propane sulfonic acid onto microcrystalline cellulose. The SAP showed high water absorption capacities in different solutions and could reach water absorption equilibrium quickly. It also exhibited high acid and alkali resistance, making it suitable for extreme conditions. The synthesized SAP can be used to improve plant growth and survival under drought and saline alkali conditions.

Summary: In enhancing oil recovery, new water-soluble polymers are developed to replace the toxic acrylamide (ACR) monomer. Acrylic acid (AA) and 2-acrylamido-2-methylamido-2-methyl-1-propanesulfonic acid (AMPS) are commonly used replacements, but they also exhibit cytotoxicity, DNA damage, cell cycle arrest, and induction of apoptosis. AA and AMPS have lower acute toxicity than ACR, but they are not entirely toxic-free. It is important to focus on the toxicity of AA and ACR to protect occupational health.

Summary: The effects of crosslinker and dye type on the swelling and adsorption properties of crosslinked polyhydroxamates were investigated. The results showed that the swelling properties of the hydrogels were greatly influenced by the crosslinker type, and the diffusion of dye solutions into the hydrogels exhibited non-Fickian behavior. It was also found that CHP could be used as an effective adsorbent for the removal of dye molecules, organic molecules, and biologically active molecules.

Summary: Selective removal of mercury(II) using radiation-synthesized hydrogels was investigated. HM/ACR hydrogels showed higher swelling parameters and better binding capacity for Hg2+ compared to HM hydrogels. The binding behavior of Hg2+ was observed to be C-type for HM hydrogels and L-type for HM/ACR hydrogels. The binding parameters were calculated using Freundlich, Langmuir, and Henry models, and the effects of various factors were studied.
