The chelating resin was synthesized by polycondensation reaction of       4-hydroxy benzaldehyde, formaldehyde and biuret under alkaline condition. The prepared resin was characterized by IR spectroscopy  and ¹HNMR spectroscopy. The resin sample was cured isothermally at 120⁰C.The DSC scans was measured  for the prepared resin. The analytical evaluation of the prepared resin toward the studied ions (Hg²⁺, Ni²⁺ and Pb²⁺) using the batch method. It was employed to study selectivity of metal ion uptake in a different pH and different treatment time.
