Abstract: The optimum conditions for synthesis of 1H-1,2,4-triazole-3-thiol resin (TATR) are as follows:molar ratio of SH∶Cl=2.5∶l in DMF, reaction temperature 80℃, reaction time 8 h. The functional group of TATR is 3.77 mmol FG/g resin. The structure of the resin has been confirmed by elementary analysis, FT-IR and XPS. The sorption capacities of TATR for Au(Ⅲ), Pt(Ⅳ) are as high as 3.71, 0.76mmol ion/g resin, respectively. The apparent activation energy of sorption of TATR for Au (Ⅲ) is 14.6kJ/mol.
