The adsorption and mechanism of Re(VII) on resin D318 were studied using chemical methods and IR spectrometry. At pH 5.2, the static and dynamic saturation adsorption capacities were 351.4 and 366.5 mg.g(-1), respectively. The adsorption behavior obeyed the Freundlich empirical equation and the adsorption rate constant k(298) was 6.37 x 10(-4) s(-1). The desorption percentage was up to 99.7% when 2.0 mol.L(-1) KSCN was used for dynamic desorption.
