Synthesisis And Applications of Natural Polysaccharide Based Ion Exchanger, Guar Gum 2-Amino-3(4-Imidazolyl) Propanoic Acid (Gaipa) Resin for Removal of Toxic Metal Ions From Industial Efflunt’s of Steel Industry, Jodhpur, Rajasthan

Natural Guar gum based resin which containing 2-amino, 3-(4-imidazolyl) propanoic acid as a functional group has been synthesized. This ion exchange GAIPA resin was used for removal of toxic metal ions from industrial effluents using the principle of ion exchange mechanism. GAIPA resin was used for removal of metal ions from reference solution containing metal ions and industrial effluents of steel industry, Jodhpur, which contained metal ions. Metal ions show maximum adsorption on GAIPA resin at pH 4-6.On this pH, resin have highest Kd value. The sequence of maximum adsorption rate of metal ions from references solutions on GAIPA resin were follow as Pb(II)>Cd(II)>Fe(II)>Cu(II)>Zn(II)>Ni(II)>Co(II)>Cr(III) and from industrial effluents follow as Fe(II)>Pb(II)>Zn(II)>Cu(II)>Cd(II). The guar gum based resin GAIPA was characterized on the basis of ion exchange capacity and FTIR.
