“…In the figure, it is seen that PVP blended HPC-Borax hydrogel have higher capacity of adsorption for Fe(III) than Cu(II) ion solution inside the hydrogel matrix in same pH environments. This is due to the fact that PVP blended HPC-Borax hydrogel becomes a polyelectrolyte hydrogel and therefore interaction between the hydrogel and of Fe(III) ion is stronger than Cu(II) ion as reported in case of carboxy methyl cellulose hydrogels with monovalent and divalent metal ions interaction [10]. The interaction between the -OH groups in hydrogel contributed from the polymers and the metal ions may have facilitates stability, and water insolubility of these polymeric matrices therefore resulting in increasing the interaction by increasing the crosslinking structure.…”

In this study, environmentally friendly hydrogels prepared from hydroxy propyl cellulose hydrogels blended with poly(vinyl alcohol) (PVA) and poly(vinyl pyrrolidone) (PVP) were employed to absorb selected metal ions of Cu and Fe to find potential applications in removal of metal ion from water or in wastewater treatment. Highest adsorption capacity of hydroxy propyl cellulose hydrogels blended with PVA or PVP is shown at 0.04 % (w/v) of the metal ion solutions. Hydroxy propyl cellulose hydrogel when blended PVA has shown greater adsorption of Fe(III) ion than Cu(II) ion at higher pH. Hydroxy propyl cellulose hydrogel when blended with PVP also showed maximum adsorption capacity rather than PVA blended hydrogel.

“…Compared to our study, the above study used a high concentration of polymers; i.e., 10% CMC and 30% AA. Sultana et al synthesized copolymer hydrogels from acrylamide/CMC by γ-irradiation, and they obtained an SD value in DI water of 795% [ 29 ]. We have shown that by using low concentrations of polymers and GO and appropriate mass ratios between them, with a moderate radiation dose rate, stable hydrogels with different degrees of swelling were obtained.…”

In this study, several superabsorbent hybrid hydrogel compositions prepared from xanthan gum (XG)/sodium carboxymethylcellulose (CMC)/graphene oxide (GO) were synthesized by e-beam radiation crosslinking. We studied and evaluated the effects of GO content from the chemical structure of the hydrogels according to: sol-gel analysis, swelling degree, diffusion of water, ATR-FTIR spectroscopy, network structure, and dynamic mechanical analysis. The gel fraction and swelling properties of the prepared hydrogels depended on the polymer compositions and the absorbed dose. The hybrid XGCMCGO hydrogels showed superabsorbent capacity and reached equilibrium in less than 6 h. In particular, the XGCMCGO (70:30) hydrogel reached the highest swelling degree of about 6000%, at an irradiation dose of 15 kGy. The magnitude of the elastic (G′) and viscous (G″) moduli were strongly dependent on the absorbed dose. When the degree of crosslinking was higher, the G′ parameter was found to exceed 1000 Pa. In the case of the XGCMCGO (80:20) hydrogel compositions, the Mc and ξ parameters decreased with the absorbed dose, while crosslinking density increased, which demonstrated that we obtained a superabsorbent hydrogel with a permanent structure.

“…This might be because of the different amount of cross‐linking in the hydrogel. As irradiation increases, the cross‐link density will increase because higher energy EB results in formation of more free radicals which can lead to more cross‐linking to occur …”

Carboxymethyl sag o pulp (CMSP)/carboxymethyl sago starch (CMSS) hydrogel was synthesized by electron beam irradiation. In the series of hydrogels prepared, 40%/20% CMSP/CMSS hydrogel had the highest gel fraction. The swelling capacity of CMSP/CMSS hydrogel was found to be highest in distilled water, followed by pH 11, pH 7.4, and pH 1.2. Scanning Electron Microscope photographs revealed that the drug-loaded hydrogel had a smoother surface than unloaded hydrogel. Fourier Transform Infrared and Differential Scanning Calorimetry analysis showed the absence of interaction between the hydrogels and the drug. All drugloaded hydrogels had drug encapsulation efficiency between 63% and 69%. CMSP/CMSS hydrogel swelled and allowed the release of drug at pH 7.4. These properties qualify the hydrogel as a potential candidate for controlled drug release at the ocular and colonic regions.
