Synthesis and Adsorption Properties for Ag(I) of Pyridinedicanbnyl Thiourea Resin


Article Preview

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°C, 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.
