“…Cadmium has various radioisotopes among which 109 Cd with a half-life of 462.9 days. It is applied in nuclear reactors as control rods and shields to absorb neutrons (Aglan et al, 2014). It also has an important role in the production of nickel-cadmium (Ni-Cd) rechargeable batteries and as corrosionprotection coating for iron and steel.…”

Herein, we investigated a facile strategy to modify the graphene oxide (GO) with sodium alginate (SA) through using tetraethylorthosilicate (TEOS) as binding agent. The GO-SA was highly loaded with carboxylated (-COO−Na+) groups which permitted for fast and efficient interaction with the metal ions. Therefore, the prepared composite was employed as an efficient adsorbent to uptake of some heavy metal from aqueous solution. The as-synthesized GO-SA was characterized with various advanced techniques before and after the removal process. The analysis of the experimental data showed that, the Langmuir model excellent fit the adsorption data with maximum adsorption capacities of 887.21, 161.25 and 139.62 mg g−1 for Pb2+, Zn2+ and Cd2+, respectively. Moreover, the GO-SA presented a good regeneration and reuse ability with enhancing in the removal percent for all the studied metal ions. In addition, the prepared composite showed a suitable selectivity for Pb2+ from Zn2+ and Cd2+ co-existed solution.

“…The composite sorbents had a strong interest due to their variation of usages in unlike fields such as water purification, chemical separation, electrochemical sensor, solar cell, optical properties, and catalyst [9,10]. Many pollutants disrupt or change the chemical structure of water in the world and affect the aquatic environment [11]. The current methods for the sorption of hazardous metals from liquid waste solutions include chemical precipitation, ion exchange, membrane, adsorption, and biosorption [11].…”

Gamma-irradiation initiated polymerization was utilized to prepare polyacrylonitrile acrylamide nano-silica {P(AN-AM)-NS}. Various analytical tools like XRD, FT-IR, SEM, TEM and DTA & TGA were used to estimate the morphology, functional groups, and structure of {P(AN-AM)-NS} nanocomposite. The ability of {P(AN-AM)-NS} nanocomposite to remove Cs(I), Pb(II), Cd(II), Sr(II), and Cu(II) ions from the multi-component system was evaluated by batch techniques considering the influence of (shaking time, pH, reaction temperatures), and capacity. At the optimum pH, distribution coefficients have selectivity order; Pb2+ > Cs+ > Cu2+ > Cd2+ > Sr2+. The kinetic data obey pseudo-second-order models. The capacity was reduced by increasing the heating temperatures of solid powder. The thermodynamic parameters showed an endothermic and spontaneous. The investigation proved that {P(AN-AM)-NS} nanocomposite is a suitable organic-inorganic sorbent for the sorption of the studied ions from liquid solutions and could be considered as potential material for purification of effluent polluted with these ions.
