Melamine–formaldehyde–thiourea (MFT) chelating resin has been prepared. Au 3+ ions uptake behavior and selectivity of the chelating resin were investigated by both batch and column methods. MFT resin showed higher affinity toward Au 3+ compared with base metal ions, Cu 2+ and Zn 2+ . The highest Au 3+ uptake values were obtained at pH 2 and Au 3+ adsorption capacity of the resin was calculated as 48 mg Au 3+ /g resin (0.246 mmol Au 3+ /g resin) by batch method. It was concluded that Au 3+ ions could be selectively concentrated from the solution including Cu 2+ and Zn 2+ base metal ions by column method. © 2007 Wiley Periodicals, Inc. J Appl Polym Sci, 2008
