Abstract

Among chelating RESINs, the amine containing RESINs which have excellent adsorption property for metal ions are especially applied widely in separation, enrichment, and removing of heavy metal ions. In this paper, new amine containing RESINs based on POLYACRYLONITRILE (PAN-DTA and PAN-TETA) were prepared through the reactions of POLYACRYLONITRILE with DIETHYLENETRIAMINE (DTA) or TRIETHYLENETETRAMINE (TETA) by a rapid, simple, and economically feasible route. The prepared RESINs which are completely insoluble in water and common organic solvents were used to remove Ni(II) ion from aqueous solutions. The sorption behaviour of the RESINs for this ion showed that the greater sorption and distribution coefficients (Kd) were obtained at higher pH media. The highest sorptions of Ni(II) on PAN-DTA50, PAN-DTA100, PAN-TETA50 and PAN-TETA100 RESINs were determined as 1.9, 3.0, 1.8 and 2.9 mmol/g, respectively. It is shown that the amine capacity of the RESINs is dependent on the volume percentage of DTA or TETA and the maximum capacity of amines obtained are 6.25 and 9.0 mmol/g for PAN-DTA100 and PAN-TETA100, respectively. Also, the recovery of Ni(II) from PAN-TETA50 and PAN-TETA100 RESINs are estimated about 65% and 61%, respectively. The RESINs and their metal complexes are studied by FTIR spectroscopy, scanning electronic microscopy (SEM), and thermal gravimetric analysis (TGA). All the analytical methods have confirmed the presence of metal in the metal-resin complexes.
