Novel conventional and chelating anion exchange resins with amino ligands for sorption of silver

2-Mercaptobenzimidazole derivative of chitosan for silver sorption – Contribution of magnetite incorporation and sonication effects on enhanced metal recovery

“…Villemin et al [17] prepared phosphonate-polyethyleneimine resins (PEI), by controlled reaction of phosphorous acid with PEI, for preparing ionexchange resins and Ag-based antimicrobial polymers. A series of imidazole-based and polyamine resins was designed for the sorption of silver from HCl solutions [18]: imidazole-based resins reveal more efficient than polyamine-based resins.…”

Silver(I) recovery on sulfur-containing polymeric sorbents from chloride solutions

“…The adsorption capacities of PTDTR for Ag(I) had a bit decrease as the increasing the concentration of Cu(II) ions, suggesting the presence of Cu(II) ions in solution had little effect on Ag(I) adsorption. The 1-methyl imidazole resin and 1,2-dimethylimidazole resin showed preferential sorption of Ag(I) in the presence of Cu(II) from synthetic chloride solution (Pilśniak-Rabiega et al, 2019). The chlorocomplexes of Cu(II) Table 9.…”

“…This solution was prepared by chloride leaching of a solid residue after atmospheric leaching in sulfuric acid of copper concentrate. Detailed procedures of chloride leaching solution obtaining are presented in (Pilśniak-Rabiega et al, 2019).…”

“…The sorption ability of resins I and II was investigated in real chloride leaching solution. This solution was prepared by chloride leaching of a solid residue after atmospheric leaching in sulfuric acid of copper concentrate (Pilśniak-Rabiega et al, 2019). Table 10 shows the effect of foreign ions on sorption of Ag(I).…”

“…Affinity order of the metals to the resin was Pb>Ag>Zn>Cu>Fe>Ni> Mg, which can be explained by the tendencies of the metals to form anionic chloride complexes, and by the Table 10. Sorption of Ag(I), Cu(II), Pb(II), Zn(II), Co(II) and Ni(II) from real chloride leach solution (CAg = 60.0 mg/dm 3 (0.556 mmol/dm 3 ), CCu = 454 mg/dm 3 (7.14 mmol/dm 3 ), CPb = 4.21×10 3 mg/dm 3 (20.3 mmol/dm 3 ), CZn = 20.0 mg/dm 3 (0.306 mmol/dm 3 ), CCo = 16.3 mg/dm 3 (0.277 mmol/dm 3 ), CNi = 5.07 mg/dm 3 (0.0864 mmol/dm 3 )CHCl = 0.10 mol/dm 3 , CNaCl = 4.0 mol/dm 3 ) affinity of the resin towards the less hydrated Pb and Ag.Polymeric resins with diethylenetriamine and tetraethylenepentamine groups have been used for the separation of Ag(I) from real chloride solution containing Cu(II), Pb(II), Co(II), Ni(II) and Zn(II) (Pilśniak-Rabiega et al, 2019). It was found that chlorocomplexes of Pb(II), Ni(II) and Zn(II) were not sorbed by the diethylenetriamine resin from chloride solution.…”
