Abstract: In this study, a novel selective Au(III) chelating surface ion imprinted fibers based on phenyl thiosemicarbazide modified natural cotton (Au-C-PTS) has been synthesized, and applied for selective removal of Au(III) from aqueous solutions. Batch adsorption experiments were performed with various parameters, such as contact time, pH, initial Au(III) concentration, and temperature. The kinetic studies revealed that the adsorption process could be described by pseudo-second-order kinetic model, while the adsorption data correlated well with the Langmuir and Freundlich models. The maximum adsorption capacities calculated from the Langmuir equation are 140 1 mg g-1 and 72 1 mg g-1 at pH 5 for both Au-C-PTS and NI-C-PTS, respectively. The estimated thermodynamic parameters (Gibbs free energy (Δ G), enthalpy (Δ H), and entropy change (Δ S)) indicated the spontaneity and exothermic nature of the adsorption process. Furthermore, the selectivity study revealed that the ion imprinted fibers was highly selective to Au(III) compared with Cu(II), Cd(II), Hg(II), and Fe(III). The adsorbent was successfully regenerated with a 0.1M HNO3 solution. 2014 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2014, 131, 40769
