Evaluation of Sorption Behavior of Poly methylenesbis(2- hydroxybenzaldehyde) For Cu (II), Ni (II), Fe (III), Co (II) and Cd(II) ions

Ortho hydroxyl compounds are having the capacity to build through phenolic oxygen and tertiary nitrogen with efficient metal cheating agents and have beenstudied as Schiff base polymers [1]. Present work describes the Schiff base polymer of [poly methylene bis(2hydroxybenzalde)1,2-phenylenediimine]condensed with formaldehyde as an adsorbent for metal ions e.g. Cu (II), Co(II), Ni (II), Fe (III) and Cd (II) with preconcentration [2], followed by desorptionand determination by atomic absorption spectrophotometer. The work also examined the kinetics of sorption [3-4], sorption isotherms andthermodynamics of sorption, for these metal ions on the resin. Data provided for both synthetic and real samples represents the resultsof this study in detail
