The natural polysaccharide-based resin of tamarind using functional group as 6-amino caproic acid has been synthesized by porath’s method. Their adsorption behavior also evaluated by determination of % adsorption of toxic metal ions from stock solution as well as industrial effluents by batch method and column separation experiment. Their physiochemical properties as bulk density, ion exchange capacity, and FTIR, were investigated. Using the batch equilibrium approach, Kd of five metal ions at various pH levels was investigated. The maximum removal % of metal ions of Cu+2, Fe+2, Zn+2, Cd+2, and Pb+2 at TACA resin were found at 97.97%,97.80%, 96.39%, 94.94%, and 91.90% respectively. Distribution ratio of these ions observed from pH 2 to 8 was Cu+2 > Fe+2> Zn+2> Cd+2 > Pb+2. The toxic metal ions from discharge samples of the metallurgical and mineral industries have been removed using ion exchange resins. Recovery of Zn (Ⅱ), Pb (Ⅱ), Cd (Ⅱ), Cu (Ⅱ), and Fe (Ⅱ) were obtained at 95.44, 96.27, 96.41, 98.82, and 100% respectively. The ion exchange capacity of TACA resin was found 2.24mmol/g
