“…Maximum adsorption capacity values obtained from prepared gels are given in Table III in comparison with similar studies in the literature, [39][40][41][42][43][44][45][46][47][48][49][50] which shows that the synthesized homo-and co-polymers in our work have the highest values.…”

In this study, N,N-dimethylaminopropyl methacrylamide (DMAPMAm) homopolymer and DMAPMAm/itaconic acid (DMAPMAm/IA) copolymers were obtained from 60 Co-c radiation polymerization. Gel fraction and percentage of swelling values were calculated through gravimetrical calculations. In order to increase the swelling of the hydrogel, the amount of IA in initial copolymer composition was gradually increased, but it was observed that gelation values were low. The structural and morphological assessments of homopolymer and copolymers were made by means of several techniques including Fourier Transform Infrared Spectroscopy (FT-IR), Scanning Electron Microscopy (SEM), and Energy-Dispersive X-ray Spectroscopy (EDS). The cobalt ion (Co 21 ) removal capacities of hydrogel were investigated by taking into account of the initial metal ion concentration and pH of aqueous medium. When it came to the maximum capacity of values obtained from adsorption experiments by using Co 21 solutions at pH 5, they changed between 220 and 245 mg Co 21 /g dry hydrogel. FT-IR, SEM, EDS, and XRD analyses were carried out for enlightening the mechanism of Co 21 removal by hydrogels after the completion of adsorption. Also, desorption studies were conducted using ethylenediaminetetraacetic acid (EDTA). Finally, within approximately 5 days, all adsorbed Co 21 ions were released from hydrogels at pH 5 using 0.1M EDTA solution.

“…As the pH increases, the positive charge density of sorption edges reduces by deprotonation reaction and some surface binding sites become negatively charged (such as :SO -), enhancing the sorption of positively charged Co(II) ions through electrostatic attraction. At high pH (pH [ 8.5), Co(II) ions start to precipitate in the form of insoluble hydroxide Co(OH) 2 and the specie of Co(OH) 3 -competes with negatively charged surface of CS-CPL composite, which contribute to the slight decrease of sorption percentage. The results are similar to the sorption of Co(II) on Ca-rectorite [5], permutite [7] and bagasse pith based sulphurised activated carbon [25].…”

“…Exposure to such ionizing radiation and acute cobalt poisoning can give rise to health problems such as radiation-induced illness like cancer or damage to vital organs [2]. Therefore, for the sake of public health and ecosystem stability, it is imperative to eliminate 60 Co concentration in nuclear discharge to permissible limits (2 lg/L) [3].…”

Chitosan-clinoptilolite composite was prepared and tested for removing radiocobalt from aqueous solution. The composite was characterized with Fourier transform infrared spectroscopy, X-ray diffraction analysis and scanning electron microscopy coupled with energy dispersive X-ray analysis. The sorption of Co(II) on chitosanclinoptilolite composite was pH-dependent and ionic strength-independent. The kinetic sorption was fitted well by a pseudo-second-order rate equation. The thermodynamic parameters (DH 0 , DS 0 , DG 0 ) revealed that the sorption of Co(II) on chitosan-clinoptilolite composite was spontaneous and endothermic. The study showed that chitosan-clinoptilolite composite had excellent potential for the treatment of wastewater containing radiocobalt.
