| Abstract: | The sorption mechanism of sulfur-containing chelating resin, poly4-vinylbenzyl (2-hydroxyethyl) sulfide], towards Au(III) was investigated by Fourier transform infrared spectra (FTIR), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), energy dispersive X-ray microanalysis (EDX), and X-ray diffraction (XRD). It was showed that the sulfide bond in the resin was oxidized into sulfoxide and sulfone bond, and Au(III) was deoxidized into Au(0). |
