Abstract: Adsorption of lead (II) ions onto powder prepared from renewable plant material which is Strychnos spinosawas investigated with the variation in the parameters of contact time, the amounts of adsorbent, lead (II) ion concentration and temperature. The experimental data were analyzed using Langmuir, Temkin and Freundlich equations. The adsorption data were found to fits Freundlich, Langmuir and Temkin models. The experiments showed that the highest removal rate was 96.79% for lead (II) ion under optimal conditions. The kinetic data for the adsorption process obeyed pseudo-second order rate equation. The Strychnos spinosa leaves powder investigated in this study exhibited a high potential for the removal of lead (II) ion from aqueous solution.
