STUDIES ON ION-EXCHANGE RESIN BASED ON [STYRENE - MALEIC ANHYDRIDE] COPOLYMER

Science

Commercial [styrene-maleic anhydride](SMA)-copolymer was treated with aniline at room temperature for 6 hrs. The resultant Phenylamine pendented [styrene maleic–anhydride] copolymer was designated as Phenylamine styrene malimic acid(PSMA). It was characterized by elemental analysis, -COOH group, -OH group, IR spectral features and thermogravimetry. The polymeric metal chelates of PSMA were prepared with various transition metal ions Cu(II), Ni(II), Co(II), Mn(II), and Zn(II). All the polymeric chelates were characterized by metal: ligand (M/L) ratio, spectral charactivities, magnetic moments and thermogravimetry. The ion-exchange properties of PSMA were evaluated by batch equilibrium method. For this the effect of electrolytes on metal uptake by polymer, rate of metal uptake by polymer and distribution of metal ion on polymer and mother liquor over wide pH range. The study also was extended to the treatment of metal industries effluents. Ultimately the so called resin can be utilized commercially for the treatment of metal pollutant water i.e. it will save environment.
