In this work, a novel polymer polyamic hydrazide (PAH) was synthesized via the reaction of terephthalohydrazide with pyromelitic dianhydride. The obtained PAH was characterized with nuclear magnetic resonance (NMR) spectroscopy, Fourier transform infrared (FT‐IR) spectroscopy and elemental analysis. Finally, a novel magnetic nanocomposite was prepared by immobilization of PAH on the Fe 3 O 4 nanoparticles in water. The prepared magnetic nanocomposite was successfully used for selective removal of Pb 2+ and Cd 2+ ions from industrial wastes and the effects of affecting parameters on the adsorption capacity of the magnetic nanocomposite adsorbent for the removal of Pb 2+ and Cd 2+ from model aqueous solutions were investigated. The maximum adsorption capacities of Pb 2+ and Cd 2+ were found to be 138.9 and 103.1 mg g −1 , respectively. The kinetics and mechanism of the adsorption of Pb 2+ and Cd 2+ on the surface of the prepared nanocomposite were studied and it was found that complex formation between active sites of the surface of the nanocomposite and metal ions is the possible mechanism for adsorption of metal cations. © 2015 Wiley Periodicals, Inc.
