Adsorption studies were carried out on used Battery Cell carbon for removal of Pb and Cd metal ions at different temperatures i.e. 35°C, 45°C and 55°C. Adsorption isotherms were studied at three temperatures and experimental data well fitted to Temkin adsorption isotherm model rather than Langmuir and Freundlich isotherm. Different models of kinetic were studied but best fitted by Pseudo second order, Bangham, Intraparticle diffusion and Elovich models at 35°C and 45°C temperatures. Adsorption effect of metal ions also analyzed by pH study at room temperature. Characterization of sample by technique BET and XRD. BET surface area was found 11.519m2/g and adsorption-desorption isotherm was monolayer-multilayer type.
