Abstract: Lead (ll) removal efficiency of polyacrylamide grafted sawdust has been investigated through la-boratory experiments. Kinetic measurements have been made as a function of solution concentration of Pb(II) ions, pH and temperature. The slow step governing the rate of exchange is diffusion of ions through the exchanger particles. The equilibrium data fit well with the Langmuir isotherms. Thermodynamic parameters were also presented to predict the nature of adsorption. Adsorbent can be regenerated with acid and can then be reused.
