dc.description.abstractHigh-capacity ion exchange resins based on Poly Methyl Methacrylate (PMMA) was developed during this study having higher mechanical strength, stable and, hydrophilic in nature compared to Poly styrene (PS) based systems. PMMA was cross-linked by Di Vinyl Benzene (DVB) to get macro porous PMMA- DVB resins by suspension polymerization. PMMA-DVB resins were surface modified by nitration followed by amination under appropriate temperature conditions. Change in the color of resin from white to pale yellow and pale yellow to golden yellow as well as characteristic peaks of NO2 at 700 cm-1 and 1400 cm-1 and 3100-3200 cm-1 for NH2group in FTIR spectroscopy confirmed the presence of NOx and NH2 groups on the surface of resin. These modified resins were evaluated with respect to the ion exchange capacity and it was found that the modified PMMA-DVB resin possessed higher capacity compared to commercial Poly Styrene- Di Vinyl Benzne resin. This may be attributed to the modification of CH3/CH2 sites of PMMA. Copyright © 2009 Tech Science Press.-
