From the author: A novel chelating resin macroporous cross-linked polystyrene immobilizing 2,5-dimercapto-1,3,4-thiodiazole via a hydrophilic tetraethylene glycol spacer (PS-TEG-BMT) is synthesized and the structure is characterized by means of Fourier transform infrared spectroscopy (FTIR), energy dispersive X-ray microanalysis (EDX), and elementary analysis. Its adsorption capacity for several metal ions such as [Hg.sup.2+], [Ag.sup.+], [Ni.sup.2+], [Pb.sup.2+], [Cd.sup.2+], [Fe.sup.3+], [Bi.sup.3+], [Zn.sup.2+], and [Cu.sup.2+] are investigated. The initial experimental result shows that this resin has higher adsorption selectivity for [Hg.sup.2+] and [Ni.sup.2+] than for the other metal ions and the introduction of hydrophilic TEG spacer is beneficial to increase adsorption capacities. The result also shows that the Langmuir model is better than the Freundlich model to describe the isothermal process of PS-TEG-BME resin for [Hg.sup.2+]. Five adsorption-desorption cycles demonstrate that this resin are suitable for reuse without considerable change in adsorption capacity. POLYM. ENG. SCI., 45:1515-1521, 2005.
