Summary:A novel functional resin, polyacrylonitrile-melamine (CPAN-M), was made through the nucleophilic addition reaction of cross-linked polyacrylonitrile (CPAN) with melamine. It was developed for the removal of Cu (II), Pb (II) and Zn (II) from aqueous solution. The sorption experiments were investigated by synthesized functional resin under different experimental conditions, such as temperature, initial concentration, pH and contact time. The results showed that the adsorption behavior of the resin for selected metal ions was found to be greater at higher pH values. The high adsorption rate (<20 min) was seen. The maximum adsorption capacity on CPAN-M was determined as123 mgg-1 for Cu (II). The adsorption kinetics followed the pseudo-second-order equation, while the adsorption isotherms were well fitted for the Langmuir model. The desorption experiments by elution of the obtained resin with a hydrochloric acid (HCl) show that the CPANM M be reused. The prepared resin and its metal chelates were characterized by Fourier transform infrared Spectroscopy (FT-IR), elemental analysis, thermogravimetric analysis (TGA), gravimetry, UV- vis spectroscopy, and atomic absorption techniques (AAS).
