| Abstract: | The Schiff base polymer derived from ethylenediamine and 2-hydroxybenzaldehyde with formaldehyde (o-HBED-HCHO) formed chelates with Cu (II) and Cd (II) metal ions. The formation of Schiff base, resin and the polychelates were confirmed by C H N analysis, infrared, UV/Vis spectra and thermogravimetric analysis. The intrinsic viscosity of resin was determined by viscometry in THF. The adsorption characteristics of resin towards Cu (H) and Cd (II) metal ions in dilute solutions were measured, which indicated metal loading of Cu (II) 84.0 % and Cd (H) 70 % at room temperature on an optimized pH 6. The effects of pH optimization, flow rate, capacity of % sorption were studied. After these optimization the resin was examined for adsorption of both Cu (II) and Cd (H) metal ions from their aqueous solutions after desorption and determination by atomic absorption spectrometry. |
