Heavy metal ions are intensively polluting water is a major environmental problem and removal of those ions is highly important because of their toxic nature. In this present study, carbonized sawdust was impregnated with poly (sodium 4-styrene sulphonate) (PSSS) to enhance the metal affinity and selectivity via surface chelating ion-exchange as well as hydrogen bonding adsorption mechanism. An adsorbent characteristic was analyzed through Scanning Electron Microscopy (SEM), Fourier Transform Infrared Spectroscopy (FTIR) and BET analysis. The process variables such as feed concentration, agitation speed, temperature effect and pH of the solution were optimized by adsorption studies for the analysis of Ni (II) ions removal. Various isotherm models were fixed with experimental data to explain the interaction of solute with adsorbent in batch studies. Kinetic behavior of different kinetic models and thermodynamic properties was also determined. The best isotherm in this study was selected by error analysis (χ2 test) and the stability of adsorbents was also confirmed through desorption studies.
