Abstract
A resin synthesized from tamarind kernel powder possesses high selectivity for metal ions. Distribution coefficients for some metal ions has been determined by the batch method. The influence of pH on ion exchange capacity and K d value of metal ions were studied. The resin has been characterized by Fourier transform infrared spectroscopy, thermogravimetric analysis, chemical composition and ion exchange capacity (IEC). The selectivity order is Pb2+ > Cu2+ > Fe2+ > Zn2+ > Ni2+. Removal of metal ions from the aqueous solution and from effluents of a steel mill has been studied.
