Phenol-Formaldehyde resin (PFR) grafted Nano-Fe2O3 & Nano-TiO2 (nFe2O3 & nTiO2) was fabricated for Cd(II), Zn(II) & Hg(II) removal using a novel polycondensation method. The present resources were carefully examined by FT-IR spectra (FT-IR), Scanning electron microscope (SEM), Energy-dispersive microanalysis (EDX), and Thermo gravimetric analysis (TGA). PFR/nFe2O3 & nTiO2 showed excellent uptake effects for Cd(II), Zn(II) and Hg(II) removal with a pseudo-second order model. The D-R isotherm models well described the equilibrium isotherm than the Langmuir’s model. Thermodynamic parameters showed that adsorptions were feasible, spontaneous and endothermic. These suggested that both electrostatic adsorption and chemisorptions were involved. The results indicated that PFR/nFe2O3 & nTiO2 could well be used as a high concert sorbent for the heavy metal ions removal from aqueous solution with a list of Cd(II), Zn(II) & Hg(II).
