摘要：Polyamine-polyurea chelating resin. was synthesized from TDI(toluendiizosiyanat) and TETA(Trietilentetraamin) and it was used in removal of cadmium (II) ions from aqueous solutions by adsorption. By using batch method, the effect of pH, adsorbent dosage, contact time and initial concentration on adsorption were investigated. The adsorbent exhibited good sorption potential for Cd (II) ions in these conditions: 60 minutes of contact time in pH:6,0 with adsorbent dosage 0,5 g/1 00 mL. Adsorption results were applied to Langmiur and Freundlich isotherm equations. As results of isotherm investigations, the adsorption results were fitted well to Langmiur isotherm adsorption model which describes chemisorption with correlation coefficient of 0,998. Maxsimum adsorption capacity 7,305 mg/g was determined. The results of the experiments show that the resin has high adsorbing capacity for Cd(II) ions.
