“…The highly selective bifunctional poly(VPA-co-GMAco-DVB) cation exchangers were synthesized by suspension polymerization [10,[11][12][13]. Table 1 and Figure 1 show the synthesis conditions, the polymerization scheme and the functionalization of the poly(VPA-co-GMAco-DVB) cation exchangers with iminodiacetic acid, respectively.…”

Poly(vinyl phosphonic acid-co-glycidyl methacrylate-co-divinyl benzene) (PVGD) and PVGD containing an iminodiacetic acid group (IPVGD), which has indium ion selectivity, were synthesized by suspension polymerization, and their indium adsorption properties were investigated. The synthesized PVGD and IPVGD resins were characterized using Fourier transform infrared (FT-IR) spectroscopy, scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS) and mercury porosimetry. The cation-exchange capacity, the water uptake and the indium adsorption properties were investigated. The cation-exchange capacities of PVGD and IPVGD were 1.2 -4.5 meq/g and 2.5 -6.4 meq/g, respectively. The water uptakes were decreased with increasing contents of divinyl benzene (DVB). The water uptake values were 25% -40% and 20% -35%, respectively. The optimum adsorption of indium from a pure indium solution and an artificial indium tin oxide (ITO) solution by the PVGD and IPVGD ion-exchange resins were 2.3 and 3.5 meq/g, respectively. The indium adsorption capacities of IPVGD were higher than those of PVGD. The indium ion adsorption selectivity in the artificial ITO solution by PVGD and IPVGD was excellent, and other ions were adsorbed only slightly.

“…[13][14][15] The 2VP or 4VP-DVB copolymer beads are synthesized by suspension polymerization technique and the porosity in the beads is controlled by mixing some inert organic liquid named diluent with monomers. [12][13][14][15][16][17][18] Two of the most desirable properties of any ion-exchanger are: high ionexchange capacity and fast ion-exchange kinetics. These characteristics could be obtained in the network materials by the functional groups present in the chemical structure and by their porosity.…”

Este artigo avalia o emprego de copolímeros porosos (a base de estireno-STY e vinilpiridina-VP, reticulados com divinilbenzeno-DVB) como adsorventes de 4-nitrofenol de soluções aquosas. Os copolímeros foram sintetizados através de polimerização em suspensão aquosa via radical livre na presença de heptano (HEP) e tolueno (TOL) em diferentes proporções como agentes porogênicos. As unidades de VP nos copolímeros foram modificadas quimicamente pela adição eletrofílica de monômeros vinílicos funcionalizados (acrilonitrila). Os copolímeros quaternizados foram caracterizados por espectrofotometria na região do infravermelho (FTIR), análise elementar (CHN), microscopia ótica (OM) e microscopia eletrônica de varredura (SEM).This article aims to evaluate porous copolymers (based on styrene-STY and vinylpyridine-VP, cross-linked with divinylbenzene-DVB) as adsorbents for 4-nitrophenol from aqueous solution. These copolymers were synthesized by suspension polymerizations in the presence of heptane (HEP) and toluene (TOL) in different proportions as porogenic agents. The VP units of the copolymers were chemically modified by the addition of the electrophilic ethylenic compound (acrylonitrile). The quaternized copolymers were characterized by infrared spectrometry (FTIR), elemental analysis (CHN), optical microscopy (OM) and scanning electron microscopy (SEM).
