Reversible exchange of Fe3+ and Al3+ metal ions nano on cobalt (II) metal–organic framework

The reversible exchange adsorption behaviour of a nano metal-organic framework (MOF) [Co2 (C24H15N6O6) (H2O)2].2H2O.]n, 1 with respect to Al3+ and Fe3+ has been studied in order to consider its application in wastewater purification. The results show that exchange of Al3+ and Fe3+ in surface of 1 takes place efficiently. The affinity of the adsorption of the metal ions by 1 was evaluated by Inductively coupled plasma atomic emission spectroscopy (ICP-AES), Powder X-ray Diffraction (PXRD) and infrared spectroscopy (IR), scanning electron microscopy (SEM) and PXRD were used for the characterization of the adsorption .The study shows that 1 can be used for the removal of Al3+ and Fe3reversibly.
