Synthesis of a Novel Hexanedioyl Thiourea Resin and its Adsorption Properties for Ag(I)

Article Preview

Abstract:

A novel hexanedioyl thiourea chelating resin(HTR) was synthesized through interfacial polymerization of hexanedioyl diisothiocyanate and polyethylene polyamine. Its structure was confirmed by FT-IR. The adsorption properties of HTR for Ag(I) were investigated by batch operation . The results show that the adsorption equilibrium of HTR for Ag(I) is achieved after 12 hour at 20°C, the equilibrium adsorption capacity is 4.56mmol/g and increases as the temperature or pH rises, 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.
