“…Swelling behavior is one of the most important properties of adsorbents that affect final efficiency on removal of metal ions such as boron and other metal ions. 14,15 For this purpose, the swelling behavior of the prepared poly(PVA/AAc) hydrogel at different AAc contents and at different irradiation doses (10,20,30, 40 and 50 kGy) was studied, and the results are shown in Figure 4. It is found that the swelling (%) decreased with the increasing amounts of AAc.…”

Various compositions of polyvinyl alcohol/acrylic acid Poly(PVA/AAc) hydrogels are prepared using of gamma radiation. The properties of the prepared poly(PVA/AAc) hydrogel and poly(PVA/AAc/magnesium oxide (MgO)) composite hydrogel were characterized by various techniques such as fourier transform infrared (FTIR), X-ray diffraction (XRD), transmission electron microscopy (TEM), and scanning electron microscopy. The TEM and XRD patterns of MgO nanoparticles indicate that the MgO with average particle size ranged from 18.11 nm to 45.6 nm. The gel (%) of the prepared poly(PVA/AAc) hydrogel with different contents of AAc increased with increasing both irradiation dose and AAc content. The swelling (%) of poly(PVA/AAc) hydrogel at different irradiation doses and different AAc contents found to be decreased with increasing both irradiation dose and AAc contents. The effect of incorporation of MgO nanoparticles into the poly(PVA/AAc) hydrogel matrix for absorption of boron from aqueous solution under various factors such as different concentrations of boron, different concentrations of MgO, and at different treatment times was investigated. From the study, the modified poly(PVA: AAc/MgO) composite hydrogel with composition (80:20 vol.%/5 wt%) has higher substitution, macroporous structure and characterized by better performance in swelling and boron uptake capacity than poly(PVA/AAc) hydrogel with composition (80/20 vol.%). The high absorption of boron indicates complex formation via ion exchange and chelation between poly(PVA/AAc/MgO) and boron due to the presence of different moieties provided by acrylic–acrylic, acrylic-PVA, and PVA-PVA.

“…The linear form of the Langmuir and Freundlich equations is as follows 56 : where C e is the equilibrium concentration of metal ion (mg/L). The q m (mg/g) represents the maximum amount of metal ions that can be adsorbed on the adsorbent and KL (L/mg) is the Langmuir isotherm constant.…”

Nowadays, radiation grafting polymer adsorbents have been widely developed due to their advantages, such as low operating cost, high efficiency. In this research, glycidyl methacrylate monomers were grafted on polypropylene polymer fibers by simultaneous irradiation of gamma-ray with a dose of 20 kGy. The grafted polymer was then modified using different amino groups and tested for adsorption of cobalt ions in an aqueous solution. Finally, the modified polymer adsorbent with a high efficiency for cobalt ions adsorption was synthesized and tested. Different modes of cobalt ions adsorption were tested in other adsorption conditions, including adsorption contact time, pH, different amounts of adsorbent mass, and different concentrations of cobalt ions solution. The adsorbent structure was characterized with FT-IR, XRD, TG and SEM techniques and illustrated having an efficient grafting percentage and adsorption capability for cobalt removing by batch experiments. The optimum conditions were obtained by a central composite design: adsorbent mass = 0.07 g, initial concentration = 40 mg/L, time = 182 min, and pH = 4.5 with ethylenediamine as a modified monomer and high amination percentage. Kinetics and equilibrium isotherms observation described that the experimental data followed pseudo-second-order and Langmuir models, respectively. The maximum adsorption capacity from Langmuir isotherm capacity is obtained equal to 68.02 mg/g.
