A new ion exchange resin tamarind triethylamine ( TTEA ) was chemically synthesised by modified Porath's method of functionalisation of polysaccharides. The prepared resin was characterised on the basis of ion exchange capacity, elemental analysis, F ourier transform infrared ( FTIR ) spectra and thermogravimetric analysis ( TGA ). Chemical resistivity of TTEA resin was assessed in several acidic, basic media. The present method is simple and rapidly applicable for the removal and recovery of metal ions from effluent of industries. The distribution coefficient ( K d ) values of metal ions have been determined by batch method. Owing to the large differences in K d values of toxic metal ions at different pH , removal and recovery of metal ions from their aqueous solutions and effluent of P uneet S teel I ndustry, J odhpur has been studied systematically. The adsorption of different metal ions on TTEA resin follows the order; Fe 2+ > Zn 2+ > Cu 2+ > Pb 2+ > Cd 2+ . The Ion exchange capacity ( IEC ) of TTEA resin was 2.04%.
