The new chelating resin Pentaethylenehexamine XAD-4 was synthesized by the reaction of Amberlite XAD-4 resin and the chelate reagent Pentaethylenehexamine. The newly prepared resin contained 0.75 mmol of Pentaethylenehexamine per gram of resin and showed weak base behavior in aqueous solutions. The capacity of adsorption of metal ions are Mg(II) 1.0×10-³, Ca(II) 1.95×10-¹, Sr(II) 2.14×10-¹, Ba(II) 2.54×10-¹, Cu(II) 7.2×10-¹, Ni(II) 2.50×10-¹, Zn(1l) 2.11×10-¹, Co(II) 2.01×10-¹, m mol per gram of the chelating resin. Also, the elution order of the alkaline-earth metal ion Mg(II), Ca(Il), Sr(II), follow by Ba(II), and for the transition metal ions are eluted to Co (II), Zn(II), Ni(II), and Cu(II) in order.
