PREPARATION AND CHARACTERIZATION OF GUARGUM 5-AMINO-1-NAPHTHOL-3-SULPHONIC ACID (GANSA) RESIN AND ITS USE FOR SEPARATION OF HEAVY METAL IONS FROM INDUSTRIAL WASTEWATER

A new guargum based resin containing 5-amino-1-naphthol-3-sulphonic acid has been synthesized and adsorption behavior for heavy metal ions has been investigated by batch and column experiment. The guargum 5- amino-1-naphthol-3-sulphonic acid resin can selectively separate heavy metal ions from industrial waste water. The GANSA resin was characterization the basis of ion exchange capacity IR spectra and thermogravimetric analysis.The GANSA resin has been used for removal of heavy metal ions Cd⁺²,Pb⁺²,Cu⁺²,Zn⁺²in aqueous solution and effluents of Prince Steel Industry,Jodhpur
