poly(vinyl phosphonic acid-co-glycidyl methacrylate-co-divinyl benzene)(PVGD) and PVGD containing iminodiacetic acid group (IPVGD) which was indium ion silectivity, were synthesized by suspension polymerization, and their indium adsorption properties were investigated. The synthesized PVGD and IPVGD resins were characterized by Fourier transform infrared (FT-IR) spectroscopy and energy-dispersive X-ray spectroscopy(EDS) and mercury porosimeter. The ion-exchange capacity, water uptake and their indium adsorption properties were investigated. The optimum indium adsorption from pure indium solution and artificial ITO solution by PVGD and IPVGD cation exchange resins were 2.3, 3.5 meq/g. The indium adsorption cacpacities of IPVGD were higher than those of PVGD. |
