摘要：
A new guar gum based guar gum 4-aminobenzoic acid [GABA] resin has been synthesized and their adsorption behavior for toxic metal ions has been investigated by batch and column experiments. An application was under taken regarding the adsorption of different toxic metal ions from effluent of Puneet Steel Industry, Jodhpur using GABA resin. The distribution coefficient value of metal ions at different pH was also studied using batch equilibration method. The different factors affecting metal ion adsorption on this substrate such as pH, treatment time, agitation speed, flow rate and temperature were studied in detail. The prepared GABA resin was characterized by FTIR, ion exchange capacity (IEC), elemental and thermogravimetric analysis. The durability and swelling studies of GABA resin were also studied. The adsorption of different metal ions. on GABA resin follows the order : Cu2+ > Cd2+ > Fe2+ > Pb2+ > Zn2+
