Water pollution is an important challenge issue for ecosystem and the removal of heavy metals and dyes from waste water has great attention. In this presence study, a high efficient ecofriendly nanostructured terpolymer has been synthesized from 4,4‐diaminodiphenylmethane, resorcinol and formaldehyde (DRF) for the first time by condensation polymerization method. The chemical structure, thermal stability, size and morphology of the synthesized DRF terpolymer were studied by various techniques such as scanning electron microscopy (SEM), Energy dispersive X‐ray spectroscopy (EDX), Fourier transform infrared spectroscopy (FT‐IR), Thermogravimetric analysis and X‐ray diffraction (XRD) analysis. The obtained DRF terpolymer was applied for the removal of Cu 2+ , Pb 2+ , Cd 2+ and Hg 2+ heavy metal ions and MB dye from waste water. The concentrations of the selected heavy metals and MB dye were analyzed by inductively coupled plasma optical emission spectroscopy (ICP‐OES) and UV/Vis spectroscopy. The metal ions adsorption properties of DRF terpolymer were investigated as a function of electrolytes, pH of the solutions, adsorbent dose, contact time and desorption/reusability. The results demonstrate that the synthesized DRF terpolymer exhibited outstanding removal performance towards Cu 2+ , Pb 2+ , Cd 2+ and Hg 2+ divalent metal ions and excellent degradation capacity for MB dye from industrial waste water. This study provides significant new resources for eco‐friendly applications.
