Synthesis and adsorption properties for Ag(Ⅰ) of pyridinedicanbnyl thiourea resin

摘要：

　　A novel pyridinedicanbnyl thiourea chelating resin(PTR) was synthesized from pyridinedicanbnyl diisothiocyanate and diethylene triarmine,its structure was confirmed by FT-IR.The adsorption properties of PTR for Ag(Ⅰ) were investigated by batch operation.The results show that the adsorption equilibrium of PTR for Ag(Ⅰ) is achieved after 14 hour at 25℃,the equilibrium adsorption capacity is 4.73mmol/g,the adsorption process accords with G.E.Boyd equation and Langmuir adsorption isotherm as well,and the silver-loaded resins can be quantitatively eluted by a solution containing 6% thiourea in 1mol/L HNO3.
