A new chelating resin, polystyrene-2-aminothiazole (PS-AT), was synthesized via one-step reaction by grafting 2-aminothiazole in a chloromethylated polystyrene polymer. Its structure was characterized by elemental analysis and infrared spectroscopy. Batch experiments were applied to investigate the adsorption properties of PS-AT for Au(III) ions. The resin exhibits an excellent selectivity for Au(III) ions in the presence of Ni(II), Cu(II), Cd(II), and Co(II) ions. The maximum adsorption capacity obtained at 308 K was 733.8 mg/g. The adsorption kinetic and equilibrium data were well fitted to the pseudo-second-order model and the Langmuir isotherm model, respectively. Desorption of gold from the resin can be achieved using 60 mL of 2 mol/L HCl-10% thiourea solution with a desorption ratio of 93.8%. The XPS data, along with IR spectra, revealed that gold was adsorbed on the surface of PS-AT in the form of chloride, and nitrogen and sulfur were involved in the chelation of gold chloride.

“…It has been proved that glucosamine can form various complexes with many metal ions such as Cu 2+ , Ni 2+ , Fe 2+ , Zn 2+ , and etc [2,3] . In our previous work, we have prepared the chelating resin, PS-GA, by the reaction of chloromethylated polystyrene with glucosamine and studied its adsorption properties for heavy metal ions such as Cu 2+ , Ni 2+ , Hg 2+ , Co 2+ , Cd 2+ , and Pb 2+ [4] . According to Pearson's hard and soft acid-base concept, the promising selective sorbent toward noble metal ions is expected from the polymers containing functional groups with donor N atom.…”

A novel chelating resin, crosslinking polystyrene-supported glucosamine (PS-GA), was prepared and its static adsorption properties for Ag(Ⅰ) were studied. The results indicated that this resin had excellent adsorption capacity for Ag(Ⅰ). The adsorption dynamics indicated that adsorption was controlled by the liquid film diffusion and the apparent activation energy Ea was 11.83 kJ/mol. Both Langmuir model and Freundlich model could describe the adsorption isothermal process of Ag(Ⅰ), and ∆G, ∆H, ∆S values were calculated. Increasing the temperature was beneficial to adsorption. The chelating resin can be easily regenerated by 2% thiourea in 0.1 mol/L HNO3 with higher effectiveness. Five adsorption–desorption cycles demonstrated that this resin was suitable for repeated use without considerable change in adsorption capacity.

A novel chelating resin, crosslinking polystyrene-supported glucosamine (PS-GA), was prepared and its structure was confirmed by FTIR, elemental analysis, and X-ray photoelectron spectroscopy. The adsorption properties of PS-GA for Au(III) were investigated. PS-GA resin possessed excellent enriching property to Au(III) ions and adsorption proportion E% could reach to about 90 shortly after 3 h. The adsorption dynamics of Au(III) showed that the adsorption was controlled by liquid film diffusion and the apparent activation energy E a was 12.91 kJ mol Ϫ1. BothLangmuir model and Freundlich model could describe the isothermal process of Au(III), and ⌬G, ⌬H, ⌬S values were calculated. The mechanism of adsorption for Au(III) was confirmed by FTIR, SEM, and XPS. The results showed that redox reaction occurred and both coordination and ionexchange existed simultaneously in the adsorption.
