英文摘要：

Several 1,4-benzenedicarbonyl thiourea resins （BTR） were synthesized through interfacial polymerization between 1,4- benzenedicarbonyl diisothiocyanate and polyamine. Their structures were confirmed by FT-IR. The adsorption properties （including the effect of adsorption time, pH, initial concentrations and temperature） of BTR-1, BTR-2 and BTR-3 for Ag（I） were investigated by batch tests. The results show that the adsorption equilibria of BTR-1, BTR-2, BTR-3 for Ag（I） are achieved after about 10 h. Their equilibrium adsorption capacities are 7.11, 6.75 and 6.23, respectively, and the adsorption process accords with G. E. Boyd equation and Langmuir adsorption isotherm as well. The adsorption capacities increase with the increase ofpH （the highest uptake values are observed at pH being about 6-7）. The thermodynamic parameters of BTR-1 were calculated. The results show that ΔH^ and ΔS^ are 6 958.8 J/mol and 64.28 J/（mol.K）, respectively, and ΔG^ at 20, 30, 40 and 50 ℃ are -11.79, -12.52, -13.16 and -13.8 kJ/mol, respectively. The silver-loaded resins can be quantitatively eluted by a solution containing 6% thiourea in 1 mol/L HNO3.
